8l8p7000aa automatic gearbox ford escape DIY repair

The site provides information on automatic transmissions
Automatic transmission schemes, variators. The principles of the units.
Repair, disassembly and assembly of automatic transmission.

We put a brake band in the body

We assemble the pump, but do not tighten the T30 bolts

screw it on, lubricating the rubber seal with oil and turn the automatic transmission

now tighten the bolts and glue the bearing with assembly grease

insert the hub into the brake drum

compress the return spring, put a stopper

we collect friction clutches and put on a Teflon seal

not always, and not often, but you need to cut!

ATTENTION-
when overhauling, do not take the automatic transmission filter noah (do not succumb to the persuasion of managers like they put everything and there are no problems)

I am very uncomfortable in front of the guys whom I sent boxes with these filters (they are from the same batch): blush2:

I publicly apologize to the tubers from the city of Tyumen and Khabarovsk: friends:

it is possible through the pump, but where did the shaft turn in the hydraulic transmission or pump?
shaft for any new 2700 for a piece of cunning hexagon

the reason is the wear of the edges or the pump wedge
knee connection - direct through hydraulic transmission body

In the event of a major overhaul, the gearbox is removed from the vehicle. At this stage, the mechanic carefully examines the condition of all systems serving the gearbox, power unit mounting supports, etc.

After dismantling from the car, the automatic transmission goes to the overhaul area. It should be noted that on this site, as well as on all previous ones, experienced craftsmen who have a higher technical education (engineering and physical) work. Here, the Ford Escape automatic transmission is repaired, and after washing and drying all parts, their fault detection is carried out, i.e. the possibility of further use of each part or the need for its replacement is determined.

If desired, any customer can be present both during the disassembly of the gearbox and during the fault detection of its parts. At the end of this procedure, a list of replacement parts is drawn up, which is then necessarily agreed with the customer. It should be especially noted that during a major overhaul, it is necessary, regardless of the state of the automatic transmission, to replace all seals and gaskets. The use of original spare parts only from manufacturers of gearboxes increases the service life of a repaired Ford Escape automatic transmission, but leads to a significant increase in the cost of spare parts. To achieve the most optimal combination of price-quality ratio allows the use of aftermarket parts, i.e. companies specializing in the production of spare parts for automatic transmissions.

Installation is carried out taking into account all technical requirements. At this stage, the failed mounting elements and auxiliary transmission service systems are replaced. In addition, during installation, preliminary adjustments are made to the elements of the external part of the control system.

Output diagnostics and car break-in. They are carried out using the same techniques as the entrance diagnostics. In addition, all previously existing fault codes are erased from the memory of the control unit.

Ford Escape 2.3l, 2WD, automatic transmission.
Good afternoon, when driving there is a small kick when switching from 1 to 2, but this is not the main thing, for some reason the oil level has increased recently, they drive somewhere 15-20 km, I stop transferring to P, check the level, ten thousand was on the middle, now it has grown, they did not do anything with the box, the oil mileage in the automatic transmission is 30 thousand km

You need to set the oil level correctly.

Hello, I changed the automatic transmission on the Ford Escape.took the car after repair, the box is working, and the steering wheel is free to float (something with a cross). I'm interested in the reason. Possibly incorrect towing or just wear of the part?

ford escape 2008 3l c1 to 2 goes to 3000 rpm going to take maybe a problem?

Such things are only with diagnostics, the problem may not be in the box initially.

Good afternoon. I have a 2004 Ford escape, 2.3L, automatic transmission, (American), after towing a heavy car in 1st or 2nd gear (I don't remember) they began to slip, what's the breakdown, will it be repaired? Thanks in advance.

The 4-speed automatic transmission CD4E has been installed since 1994 on the popular front-wheel drive with engines of 2.0 - 2.5 liters Mazda 626, Tribute and MX6 (LA4A-EL). Ford began to put them on the Probe, and later, having worked out the design and eliminating the main childhood diseases, and on the Mondeo, Escape and Fiesta (according to the new Ford classification - 4F44E).

CD4E is a very simple, proven and cheap automatic transmission, one of the leaders of the Ford-Mazda automatic transmission family in terms of popularity in our repair shop.

Her predecessor - 4EAT-G (G4A-EL) has related structural weaknesses.

This automatic transmission has established itself as quite competitive in terms of price / quality ratio, and therefore, with minor modifications, it was installed at regional plants until 2007, having lived in production for convincing 13 years.

With each overhaul of the box, filter No. 246010 is replaced. The filter has a felt membrane. The oil in the young box changes about every 60 tkm, if the driver did not kill the box with harsh operating conditions (read the Recommendations for the operation of machines). Checking the oil level and quality should be done at the same time as servicing the engine - a dirty color indicates the need for replacement, and the smell of burnt oil is a marker of the need to overhaul the box. Every second oil change on a young car, automatic transmission masters advise changing the filter. And after runs for 150 tkm - change with each oil change.

Craftsmen consider the construction CD4E rather weak for 3-liter cars and "bread" for repair. Mainly due to the fact that it is installed on long-lived unique cars, it is maintainable and, after a simple repair, it reaches very high mileage. Something like the American 5HP19 (on BMW-Audi-VW).

After the modification in 1997, many typical flaws were eliminated, the new modification received a more modern hydraulic plate and control, and the best design solutions were used in the next best-selling Ford - 4F27E, which was no longer aggregated with engines more powerful than 2.3 liters.

Since 2003, the second life of this machine has begun on American cars Ford and Mazda Tribute. Repair of this very technologically advanced box with a bulkhead of consumables is carried out many times during a lifetime, and experienced craftsmen do it with their eyes closed, as they disassemble and assemble a Kalashnikov assault rifle.

Pick up repair kits - press the button.

Repair kits for gaskets and oil seals (246002) are different for cars made before 2002 and from 2003.

About half of the sales of Overolkits is made by a high-quality repair kit for ATOK 246002A gaskets. The rest are in Prescription and slightly less in Transtek.

Clutch kits are ordered and changed in every second overhaul - No. 246003. Equally often ordered original (BorgWorner + Exedi) and non-original clutches. The clutches here do not burn because of the quality of the lining, but from a lack of oil pressure. The original ones burn a couple of days a week later.

Quite often they order a complete set of steel discs - 246004

They almost always change the pistons and repair the torque converter - 246001.

Often a complete repair kit is ordered for the bulkhead of the box - Masterkit 246007. The order for the bulkhead must include a filter, a brake band and a pump bushingbelow). The rest is revealed after opening.

Typical problems of age-related automatic transmissions CD4E (LA4A-EL)

- Brake band O. Drive (No. 246020), stop break. The problem manifests itself in the disappearance of 2nd and 4th gears.

Increased pressure or vibration are often cited as causes.

Servo pistons 246902 and 246904 are often ordered along with the tape. And the drum piston Reverse - 246966.

- Overdrive tape servo (246902) is fixed with a retaining ring, which is often inaccurately installed, from which it falls out when driving. The peculiarity of this machine is that the brake band can be replaced without removing the transmission.

Electrician at CD4E quite simple and reliable, only the one that has exhausted its service life changes - Solenoid block - No. 246420.

The solenoid block has various modifications until 1996, since 1999, but for repair most often they order a universal solenoid block from Borg Warner .

The exhausted solenoid resource and extreme acceleration are usually called the primary cause of many "glitches" with low or high oil pressure, which leads to the combustion of the Forward drum.

In every second overhaul CD4E have to be changed - Set of bushings No. 246030 ,

Depleted automatic transmission bushings are a sign of a transmission that suffered from a lack of oil and abnormal dynamic loads.

The first is the ForvadDirect double drum bushing - 246048. Behind it, the torque converter hub bushing is broken - No. 246031. Pump oil seal - 246070.

From "iron" in the first place for repairs - Double Drum, (Clutch basket) Forward / Direct (6 Cylinder) - No. 246554E. Tears out the retaining ring or the pistons burst, which leads to the combustion of the clutches and rubber of the pistons. The reason is called the liberal computer settings, which allow the solenoid block to overload packets.

The drums differ by year of manufacture: before year 98 (246554A) and after year 98 (246554B). Difference in ring groove height. On right.

The problem is that the transmission “does not pull”. With the repair of the drum, the clutches and steel discs of both drums are changed - 246106 and 246108. Together with steel and backing discs. It is worth checking the bushing of this drum - 246048. It is the first bushing among the other bushings to wear out and needs to be replaced to prevent vibration and loss of oil pressure.

Ford constantly improved this drum, releasing new modifications that differ in the years of production (before 98 and after), in engine power (2 and 2.5 liters), etc. The pistons of this package have also been modified - 246964, 249969.

The oil pump often fails - due to pieces of metal ( be careful - the pump breaks down more often when disassembling the automatic transmission !! ).

Due to the high price, original pumps are almost never found, so a non-original (246500) is usually ordered for replacement.

In case of careless handling of the pump, even from a slight impact on the stator, pieces of metal are crumbled, which leads to the need to replace it !!

Another common problem is that the pump drive shaft 246671 breaks from overloads.

The rubber of the pistons is aging due to overheating (due to the same problem of oil starvation and overheating)

In half of the cases, the craftsmen order the piston of the package separately Reverse -# 246966

Often to replace pistons CD4E buy a complete gasket repair kit (Overol kit) with pistons (246002AP).

Structurally weak link CD4E : –

Planetary row Forward 246582. He is the first to withstand the extreme loads from the engine.

The reason is a broken bearing 246235 (click on the diagram on the right). Its debris breaks the entire unit, including the sun 246612 and the overrunning clutch Forward 246646.

For motors approx. 3 liters developed the more powerful Planet 246582A - for 4 satellites. Problems with her happen much less often.

With the Forward Planet can also break the Crown Gear, RingGear, (Forward) # 246592 -RB. Which is also restored or replaced with a BU.

All these problems are often associated with wear of sleeve bearings, which should be replaced as soon as there is an abnormal noise. And with the very first replacement of the brake band.

- Washer - thrust plain bearing, has 4 lugs for fixing. (No. 246231).

- Thrust bearing, (Forward planet) between planetary gear set 582 and sun gear 612 - No. 246235.

Oil shortage problems and associated vibrations hit the steel bearings, chunks and needles from which cause unpredictable damage to the CD4E gland.

If one of the bearings is worn out, then this often indicates the end of the resource and the rest. And the masters in half of the capermonts change the whole set of bearings - No. 246201. Replacing all bearings prevents many future problems with the rest of the hardware.

Have CD4E rather gentle torque converters for such engines.

The most common problem is the production of the hub bushing of the gas turbine engine - 246031. The problem is associated with insufficient oil pressure, overload and overheating.

Preventive maintenance of the gas turbine engine should be carried out at the first arrival in the overhaul after running 130-150 tkm. Hand over the "donut" for repair - 246001.

In "old age" the drive chain changes. (No. 246700).

It is different in design (45 and 46 links) for engines with a volume of 2.0 l and for 2.5 l engines.

In this node worn out during long-term use, the tape abrades the drum itself (Reverse Drum) No. 246556 .

The Drum Reverse itself is changed in 20% of cases of tape replacement.

The sensors are working out their resource: - Sensor of input revolutions 246438 and output revolutions - 246436

- Another not so common problem with age-related automatic transmissions CD4E : Teeth at the differential are worn out (no. 246715). During overhaul and bulkhead, its condition should be checked.

This repairable box is very fond of owners who do not mind tinkering with their car and craftsmen who teach or themselves learned their art from it.

And they are often scolded by those who do not like to get under the hood of their age-old car. CD4E has no pitfalls during repair and does not require adaptation, spare parts for it are inexpensive, always easy to buy.

The automobile concern Ford is one of the oldest and most successful in the world. It is to the Ford plant that the world owes the first developments in the field of planetary hydraulic automatic transmissions. Ford strives to produce reliable, comfortable cars that can compete with any car manufacturer. Ford automatic transmissions are simple and reliable.

Car Ford Focus Sedan

The Ford Focus is equipped with a unique 4f27e four-speed transmission. The uniqueness of Focus with 4f27e automatic transmission is that it is the only popular transmission that can be completely repaired without removing it from the car. This simple and reliable transmission is still in production today.

At first, Focus with automatic transmission 4f27e does not require anything other than changing the oil and filters. But already in the first years on the Focus with 4f27e, the main problems begin to appear. The first to focus on the 4f27e are the reverse clutches and the overdrive mode. On Mazda cars with the same boxes, manufacturers very quickly switched to reinforced clutches, which can also be ordered for the Ford Focus with 4f27e. Rapid burnout of clutches on Focus with 4f27e is associated with the design of the box and cannot be cured. It's all to blame for the drum seat on the Focus with 4f27e, it wears out too quickly and oil starts leaking from the back cover. Its wear occurs with increased side loads and aggressive driving, the automatic transmission electronics are very fond of overloading this unit. With oil starvation, the clutches begin to slip and burn.

Automatic transmission control unit 4f27e

A common problem with the Ford Focus automatic transmission is the rear cover. When the first vibrations appear when driving a Ford Focus, you should watch it and change it if necessary. After the clutches on the Ford Focus burn out, the drums will also start burning. Together with the drums, the pistons should be replaced immediately.

The brake band on a Ford Focus can be considered a consumable item. If it is not changed in time, the car will be left without second and fourth gears. The problem can be solved by ordering a reinforced tape.

With frequent overheating of the box on the Ford Focus, the overdrive mode servo fails.

Teflon o-rings for the oil pump and rear cover are another fun part of this automatic transmission and are sold separately. They can be changed simultaneously with the oil change, they are so “good”. Fortunately, this procedure on a Ford Focus is very simple and there is no need to dismantle the box. More relevant for Mazda vehicles than Ford Focus. If the rings on the Ford Focus are not changed, the oil will start to drain and the lack of pressure will kill the box very quickly, starting, as a rule, with reverse gear and overdrive mode. If you just add oil, then the cover or drum will have to be changed.

The electrical part of this automatic transmission is very reliable. Once every 150,000-20,000, it is necessary to rinse and clean the valve body and change its sealing elements. On the same run, along with this operation, it is worth changing the pressure solenoid and the switching solenoid. They work harder and deplete their resources faster.

On the mechanical part, one of the differentials is often grinded. After serious runs, in most cases, all plastic and rubber elements fail. The oil pump and bearings fail somewhat less frequently. The condition of the iron (gears, planetary gear, and so on) is highly dependent on the oil and operating conditions. If the owner did not like to change oils and liked to press on the gas, then, most likely, there are enough broken places in the box. In general, the box is very simple and maintainable.

CD4E automatic transmission was installed on Ford Escape and Mondeo cars. The reliable, simple and unpretentious four-speed automatic transmission quickly became a hit for engines up to 3 liters.

The electrical part of the Escape and Mondeo automatic transmission control unit is very reliable. The only thing that needs to be replaced during the overhaul of the Escape and Mondeo automatic transmissions is a set of solenoids and a speed sensor.

CD4E automatic transmission for Ford Mondeo and Escape

Over time, their resistance increases, they become clogged with dirt, leading to abnormal operation of the Escape and Mondeo automatic transmissions.

The mechanical part is also very reliable. During a major overhaul, the clutch drums and steel discs are replaced. The first symptom of their failure on the Escape and Mondeo automatic transmissions is the loss of dynamics when the car accelerates.

If one or more mechanisms inside the Escape and Mondeo automatic transmission box fail and the oil becomes clogged with metal or plastic particles, the oil pump may fail

The disappearance of the fourth and second gear knobs on the Escape and Mondeo automatic transmissions when switching the selector lever is a symptom of damage to the brake band. At high mileage and poor condition of the box, increased pressure or vibration occurs inside it, which leads to the destruction of the brake band.

If the overdrive selector mode disappears on the Escape and Mondeo automatic transmissions, this is due to the destruction of the retaining ring.

One of the advantages of the Escape and Mondeo automatic transmissions is that the Ford automatic transmission can be repaired on a lift without dismantling the automatic transmission.

If the car drives for a long time with a worn out brake band, reverse gear may also fail.

Pistons and their rubber construction are a classic problem. Rubber loses its properties over time and ceases to hold pressure.

The planetary row of forward speeds is a weak point in the design of this box. The safety margin does not correspond to the power of the engines and, if driven frequently before the cut-off, the bearings may break. If they break, then their remains are carried by oil through the mechanisms of the box and cause severe damage to it.

The same picture can be obtained if the bearings are operating in oil starvation mode.

Torque converters in this automatic transmission are not the most reliable and quickly deplete their resource, they really do not like operation in case of overheating and lack of oil.

The 5R55N automatic transmission has been used for real powerful American cars: jeeps and full-size powerful sedans like the Ford Explorer, for example.

Gaskets, oil seals and seals are changed at the time of the overhaul of the automatic transmission Explorer.

Brake band of the overdrive mode of the automatic transmission Explorer does not like distortions and vibrations, usually when they fail, they change the bands for reverse gear.

Ford Explorer with automatic transmission 5R55N

For the electrical part of the automatic transmission Explorer - a solenoid block and a speed sensor. They work in a more loaded mode and fail faster.

The automatic transmission oil pump Explorer has a very weak valve, which is better to change to an analog from the Sonnax company.

DO NOT SPEND MONEY ON REPAINING!
Now you yourself can remove any scratch from the body of your car in just 5 seconds.

In America, a frequent repair is the rebuilding of the torque converter. For them, special repair kits are produced. Torque converter failure is typical most often associated with its slip modes and aggressive driving style. On cars with this automatic transmission, it is recommended to install an additional radiator.

Ford Fiesta is equipped with a six-speed automatic transmission Powershift. Powershift is a new generation of transmission that provides economical fuel consumption. Powershift automatic transmissions are 9% more efficient than electro-hydraulic transmissions and are lighter in weight. The Powershift design consists of two separate transmissions, one responsible for shifting the even gears, the other the odd ones. The Powershift scheme is somewhat reminiscent of a manual transmission with a dry clutch, but the computer controls the shifting, manual shifting, possibly using a selector.

Powershift has the same negative points as robotic transmissions. They translate into vibrations and hard gear changes when driving aggressively.

Powershift automatic transmission for Ford Fiesta cars

Powershift is a new development and its breakdowns and childhood illnesses have not yet been studied enough. Poor factory firmware of the Powershift control unit greatly reduces driving comfort and quickly destroys the transmission mechanisms. Europe has already solved this problem with an upgraded firmware, but it has not yet reached Russia. So far, Powershift suffers from fast release bearings and oil seals coming out of the stand.

Most modern Ford automatic transmissions are maintenance-free. However, the oil and filter on such boxes still need to be changed. It is not in the rules of Russian motorists to buy a new car every three years. With a timely oil change and compliance with the operating rules of automatic transmissions, Fords live for a very long time and need major repairs after 200,000-250,000 kilometers. It is not possible for a motorist to carry out overhaul operations in Mnevniki without appropriate knowledge and experience, so it is better to entrust it to professionals.
