We put the brake band in the body

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

fasten, lubricate the rubber seal with oil and turn the automatic transmission

now we tighten the bolts and glue the bearing with mounting grease

insert the hub into the brake drum

compress the return spring, install the stopper

we collect frictions and put on a Teflon seal

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

ATTENTION-
when sorting, do not take the automatic transmission filter on it (do not succumb to the persuasion of the menagers like they put everything and there are no problems)

I am very uncomfortable in front of the guys to 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 hydrotrans or pump?
shaft for any new 2700 for a piece of tricky hexagon

cause-wear faces or pump wedge
connection with the knee - direct through the body of the hydrotrans

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

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

If desired, any customer can be present both during the disassembly of the gearbox and during the inspection of its parts. At the end of this procedure, a list of replaceable parts is compiled, which is then necessarily agreed with the customer. It should be especially noted that during the overhaul, it is necessary, regardless of the condition of the automatic transmission, to replace all seals and gaskets. The use of original spare parts only from manufacturers of gearboxes increases the life of the remanufactured 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 made taking into account all technical requirements. At this stage, the failed fastening elements and auxiliary transmission maintenance 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 running-in of the car. They are carried out according to the same methods as the input diagnostics. In addition, all previously appeared 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 slight kick when switching from 1 to 2, but this is not the main thing, for some reason the oil level has recently increased, they drive somewhere 15-20 km, they stop, I transfer to R, I check the level, ten thousand ago I was on in the middle, now it has grown, they didn’t 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 Ford Escape.took the car after repair, the box works, and the steering wheel is in free float (something with a cross). I'm interested in the reason. perhaps not correct towing or just wear of the part?

ford escape 2008 3l s1 to 2 goes at 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 Ford escape 2004, 2.3l, automatic transmission, (American), after towing a heavy car in 1st or 2nd gear (I don’t remember), they began to slip, what is the breakdown, can 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 in 2.0 - 2.5 liters of the Mazda 626, Tribute and MX6 (LA4A-EL). Ford began to put them on the Probe, and later, having worked out the design and eliminated the main childhood diseases, 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-Mazdovsky family of automatic transmissions in terms of popularity in our repair.

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

This automatic transmission proved to be 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 a convincing 13 years.

With each overhaul of the box, filter No. 246010 is changed. The filter has a felt membrane. The oil in a young box changes approximately every 60 tkm, if the driver did not kill the box with harsh operating conditions (read Recommendations for the operation of automatic machines). Checking the level and quality of the oil 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 rebuild 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.

Masters consider the design CD4E rather weak for 3-liter cars and “bread” for repairs. Mainly due to the fact that it is installed on long-lived unique cars, it is maintainable and after a simple repair it goes up to very high mileage. Something like the American version of 5HP19 (on BMW-Audi-VW).

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

Since 2003, the second life of this machine began on American Ford and Mazda Tribute cars. The repair of this very technological 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 take apart a Kalashnikov assault rifle.

Pick up repair kits - press the button.

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

Approximately half of the sales of OverolKitov are high-quality gasket repair kit ATOK 246002A. The rest - fall on Precision and a little less on Transtec.

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

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

The pistons are almost always changed and the torque converter is repaired - 246001.

Often, a complete repair kit is ordered to rebuild the box - Masterkit 246007. It must be included in the bulkhead order with a filter, a brake band and a bushing for a gas engine pump (below). The rest is revealed after opening.

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

– Brake band O. Drive (No. 246020), breakage of stop. The problem manifests itself in the disappearance of 2 and 4 gears.

Causes are often cited as high pressure or vibrations.

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

– The Overdrive belt servo ( 246902 ) is fixed with a retaining ring, which is often inaccurately installed, causing it to fall out when driving. A feature of this machine is that the brake band can be replaced without removing the transmission.

electrician CD4E quite simple and reliable, only the exhausted resource changes - Solenoid Block - No. 246420.

The solenoid block has various modifications until 1996, since 1999, but for repairs, a universal solenoid block from Borg Warner is most often ordered .

Exhausted solenoids and extreme overclocking are usually called the primary cause of many "glitches" with oil pressure, low or high, which leads to the combustion of the Forward drum.

In every second overhaul CD4E must be changed – Bushing kit no. 246030 ,

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

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

From the “iron” in the first place for repairs - double Drum, (Clutch basket) Forward / Direct (6 Cylinder) - No. 246554E. Pulls out the retaining ring or bursts the pistons, which leads to the combustion of the friction clutches and the rubber of the pistons. The reason is called the liberal settings of the computer, allowing the block of solenoids to overload packages.

Drums differ by year of release: before '98 (246554A) and after '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 friction clutches and steel disks of both drums are changed - 246106 and 246108. Together with steel and supporting discs. It is worth checking the bushing of this drum - 246048. It is the first among the other bushings to wear out and needs to be replaced to prevent vibrations and loss of oil pressure.

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

The oil pump often fails - due to pieces of metal getting into the gears ( be careful - the pump breaks 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 blow to the stator, pieces of metal crumble, which leads to the need to replace it !!

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

Piston rubber aging due to overheating (due to the same problem of oil starvation and overheating)

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

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

Structurally weak link CD4E : –

Planetary gear set Forward 246582. He is the first to not withstand the maximum load from the engine.

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

For engines approx. 3 liters developed a more powerful Planet 246582A - for 4 satellites. Problems with it happen much less often.

With Forward Planet can also break Ring Gear, RingGear, (Forward) #246592 -RB. Which is also restored or changed to BU.

All these problems are often associated with the wear of plain bearings, which should be changed as soon as extraneous noises are heard. And with the first brake band change.

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

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

The lack of oil problems and the associated vibrations hit the steel bearings, pieces and needles from which cause unpredictable damage to the CD4E hardware.

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 capermen change the entire Bearing Kit - No. 246201. Replacing all bearings prevents many future problems with the rest of the hardware.

At CD4E quite gentle torque converters for such engines.

The most common problem - GDT hub bushing - 246031 is being developed. The problem is associated with insufficient oil pressure, overloads and overheating.

Preventive maintenance of a gas turbine engine should be carried out at the first visit to the overhaul after a run of 130-150 tkm. Hand over the “donut” for repair - 246001.

By "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 liters and for 2.5 liters engines.

In this node worn out the tape during long-term operation wears out vibrations and the Drum itself (Reverse Drum) No. 246556 .

The Reverse Drum itself is changed in 20% of belt replacements.

The following sensors are exhausting their resource: - Input RPM sensor 246438 and output RPM sensor - 246436

– Another not so common problem of age automatic transmissions CD4E : the teeth at the differential are worn out (No. 246715). During the overhaul and bulkhead should check its condition.

This repairable box is much loved by owners who don't mind tinkering with their car and craftsmen who teach or have learned their art from it.

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

The Ford automobile concern 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. Automatic transmissions from Ford are simple and reliable.

Ford Focus Sedan car

A unique four-speed 4f27e transmission is installed on the Ford Focus. The uniqueness of Focus with automatic transmission 4f27e 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 Focus with 4f27e, the main problems begin to appear. The first to Focus with 4f27e are the reverse gear and overdrive clutches. On Mazda cars with the same gearboxes, manufacturers very quickly switched to reinforced clutches, which can also be ordered for Ford Focus with 4f27e. The quick burnout of the clutches on the Focus with 4f27e is due to the design of the box and cannot be cured. The drum seat on the Focus with 4f27e is to blame for everything, it wears out too quickly and oil begins to leak from the back cover. Its wear occurs with increased lateral loads and aggressive driving, 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 a Ford Focus automatic transmission is the back cover. When the first vibrations appear when driving a Ford Focus, it is worth looking at it and changing it if necessary. After the clutches burn out on the Ford Focus, the drums will also start to burn. Along with the drums, the pistons should also be changed 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 tailgate are another fun part of this transmission and are sold separately. You can change them at the same time as changing the oil, they are so “good”. Fortunately, this procedure on the Ford Focus is very simple and does not require dismantling the box. More relevant for Mazda cars than for Ford Focus. If the rings on the Ford Focus are not changed, the oil will start to leak and the lack of pressure will kill the box very quickly, starting, as a rule, with reverse gear and overdrive. 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. Every 150,000-20,000 it is necessary to rinse and clean the valve body and change its sealing elements. At the same run, along with this operation, it is worth changing the pressure solenoid and the switching solenoid. They work harder and work out their resource faster.

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

The CD4E automatic transmission was installed on Ford Escape and Mondeo cars. 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.

Automatic transmission CD4E 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, clutch drums and steel discs are changed. 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 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 is a symptom of damage to the brake band. On long runs 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 Ford automatic transmission repairs can be carried out on a lift without dismantling the automatic transmission.

If the car is driven for a long time with a worn brake band, the 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 gear set of forward speeds is a weak point in the design of this box. The margin of safety does not correspond to the power of the engines, and with frequent driving to cutoff, the bearings may break. If they break, 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 operate in oil starvation mode.

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

The 5R55N was used for real high-performance American cars: Jeeps and full-size high-performance sedans such as the Ford Explorer, for example.

Gaskets, oil seals and seals are changed when the Explorer is overhauled.

The brake band of the overdrive mode of the automatic transmission Explorer does not like distortions and vibrations, usually when they fail, the bands are also changed for reverse gear.

Ford Explorer with automatic transmission 5R55N

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

The oil pump of the automatic transmission Explorer has a very weak valve, which is better to change to an analogue from Sonnaks.

DON'T SPEND MONEY ON REPAINTS!
Now you can remove any scratch from the body of your car in just 5 seconds.

In America, a frequent repair is the restoration of the torque converter. Special repair kits are produced for them. Typical torque converter failure is most often associated with its slippage patterns and aggressive driving style. It is recommended to install an additional radiator on cars with this automatic transmission aged.

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

Powershift has the same negative points as robotic gearboxes. They are expressed in vibrations and hard gear shifts with an aggressive driving style.

Powershift automatic transmission for Ford Fiesta

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 causes transmission mechanisms to fail faster. In Europe, this problem has already been solved with an upgraded firmware, but this has not yet reached Russia. So far, Powershift has been suffering from throwout bearings and oil seals that are quickly out of standing.

Most modern automatic transmissions from Ford 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, automatic transmissions Ford live a very long time and need major repairs after 200,000-250,000 kilometers. It is not possible for a motorist to perform major repairs in Mnevniki without the appropriate knowledge and experience, so it is better to entrust it to professionals.
