DIY auto repair mazda tribute

In detail: do-it-yourself auto repair Mazda tribute from a real master for the site my.housecope.com.

The Mazda automobile concern, unlike its competitors, does not particularly like to experiment with transmissions. After unsuccessful attempts to curb rotary engines in the 80s and 90s, Mazda decided to make quiet and successful cars. Typically, the transmissions used on Mazda vehicles are time-tested, reliable designs. In the middle of the 2000s, Mazda nevertheless went for the modernization of transmissions due to new requests and competition. But this time they were ingenious revisions and upgrades of existing circuits that did not spoil anything and left their transmissions reliable, easy to repair and unpretentious in everyday driving and operation. A car service anywhere in the world can easily handle the repair of Mazda boxes.

The second generation of the sixth model, the Mazda 6 GH, received the TF80SC automatic transmission. The family of these machines is designed for engines from two to five liters, with a torque of up to 450 Nm. The latest modifications of this automatic transmission are a masterpiece of engineering. Mazda engineers managed to fit the machine into the engine compartment with their own hands and provided very fast and smooth switching. The Mazda 6 GH automatic transmission allows you to drive fast, economically and at the same time it is very reliable and not subject to overheating, like modern counterparts, and easily competes with preselective gearboxes.

The weak point of the Mazda 6 GH automatic transmission is traditional for six-speed transmissions. The Mazda 6 GH torque converter still uses a friction lining, which mercilessly wears out and clogs the box with its decay products. The lock in this automatic transmission is traditional and is not used constantly, as in modern cars. The automatic transmission of the Mazda 6 GH, like its counterparts, is subject to the combustion of clutch packs. Usually starting in second gear or reverse. After burning at least one, all the other friction clutches of the Mazda 6 GH automatic transmission will be saturated with burnt oil and will soon fail.

The valve body needs to be cleaned every 150,000-200,000 kilometers, this requires a visit to a car service. It will be problematic to dismantle the box with your own hands and flush it. Rubberized pistons during our winter tan in a few years and need to be replaced. Automatic transmission Mazda 6 GH is very sensitive to oil, it is better to pour only the original.

Mazda Demio was equipped with a four-speed automatic transmission 4F27E. This "workhorse" is still produced today. Major faults are usually associated with dirty oil. The first to suffer on the Mazda Demio are the overdrive and reverse gear clutches. This is a classic Mazda Demio problem associated with the design features of the automatic transmission. This happens due to the wear of the seat on the Mazda Demio automatic transmission drum and subsequent oil loss. The Mazda Demio computer is overloading this node unnecessarily. The consumable tape on the Mazda Demio is considered a consumable. The piston of the overdrive package often changes, especially if the box has traveled with overheating. Teflon rings of the rear cover and pump can be considered consumables and can be changed along with changing the oil and filter. The electrics and automatic transmission valve body are very reliable and rarely require repair.

Mazda Premacy was equipped with an automatic transmission of the 4EAT-G series. This is the first automatic transmission Mazda, which began to implement electronic control. A significant proportion of calls for the repair of this automatic transmission ends with the replacement of torque converter oil seals and various gaskets. A car service usually considers such work easy. Of the clutches on Premasi, packages of third and fourth gears usually burn out. Of the electronics, the line pressure and torque converter lock-up solenoids are the first to fail.For age machines, it is better to change the entire set of solenoids. When driving for a long time with a low oil level or with a dirty box, bushings and seals wear out quickly. This usually manifests itself in increased vibration when driving a car. In the event of their appearance or intensification, you should not wait for a denouement, but immediately go to a car service.

Mazda MPV was equipped with a G4A-EL box. These automatic transmissions usually go to the MVP for a long time, but they arrive already in poor condition. Usually, the entire set of clutches is immediately changed to the MPV. Various gaskets that leak oil are aging, they should also be changed as soon as possible. The gasket and seals of the pump are the weak point of the MPV. The electrics are very reliable and rarely fail, with the exception of the solenoids, of course.

Mazda Tribute was equipped with a CD4E box. This very simple and reliable four-speed transmission has become very popular. For three-liter engines, this transmission is rather weak, but it runs for a very long time on less powerful engines, it is simply repaired and drives the same amount. The best design solutions from it were implemented in 4F27E. The first thing that develops its resource in this automatic transmission is the block of solenoids. It all starts with the abnormal and incomprehensible operation of the automatic transmission, which receives increased or reduced pressure. In second place is usually the speed sensor, over time it begins to "lie" and "confuse" the electronic control unit.

Mazda 3 models were equipped with a four-speed automatic transmission 4F27E, a relative of the CD4E. This is a unique box, it can be repaired without removing it from the car. Repair work can be carried out by any car service where there is a lift. Its problems are similar to the rest of the line of automatic transmissions produced for the automaker Mazda.

Mazda Familia was equipped with a four-speed automatic transmission FN4A-El. The same is installed on the Ford Focus.

The clutches are reinforced here compared to the Ford. The overdrive and reverse packages are close in resource to all other friction clutches and have ceased to be a weak point. But no one is immune from this if there are oil leaks. Aggressive riding results in increased side loads on the caliper, causing the drum to skew. Its shrink ring can jam and the drum will begin to slip, turning a gap through which oil will ooze.

After the aging of the overheated rubber of the pistons, chips and dirt can get into them, which will also lead to burnout of the clutch packs.

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

On Mazda cars, the metal of the back cover is softer than on Ford, so sometimes there are problems with it. The cover is to be restored.

Teflon o-rings are consumables, they are easily worn out during the operation of the car. This is a design feature and nothing can be done about it. However, the engineers provided for the possibility of replacing the rings without removing the automatic transmission, for which special thanks to them. Worn rings will begin to leak oil and the box can be seriously damaged from this.

Also, for leaks, it is worth checking the seals and gaskets of the pump. If it came to replacing them on the pump, it is better to change the bushings as well.

The electrical part of this automatic transmission is very reliable, but the valve body gaskets also require periodic replacement.

Some transmissions from Mazda are so popular, common in the world and simple that they learn how to repair automatic transmissions.
