4r75e Transmission, All You Need To Know

​

When you are dealing with a 4r75e transmission that has broken down, you have an option to either have it remanufactured or refurbished. Newer transmissions, referred to as 4r75e or 4r75w, have modifications that complement Fords using an added turbine speed sensor and a more powerful microprocessor. The 4r75e transmission offers some significant revisions and improvements, making it more durable and a lighter duty transmission alternative to the 4r70. This type of 4r75e transmission for sale is mostly found in 4.6L engines and the bigger V-8 models with a 5.5L.

​

The 4r75e transmission is a revised version of the Ford 4r70w transmission introduced in the market in 2003. This transmission comes with a more powerful ring gear that can hold up to 24 lugs, a new torque converter, a vehicle speed sensor (VSS) to compliment the Output shaft sensor (OSS) improved front pump assembly. These improvements make the 4r75e able to handle more power while working efficiently and economically.

4r75e Transmission Problems

​

Some of the most common transmission issues of 4r75e include overheating, slipping between gears, hard slams when the transmission engages reverse or drive, and erratic up and downshifts. The most common causes of these transmission issues are driving on mountain roads where you need to continually shift the transmission, towing heavy loads, and going against traffic.

​

When It comes to overheating problems, the transmission breaks down when moving parts inside create more friction heat than what the AFT can get rid of. Most of the 2005-2006 Ford's are equipped with the 4r75e transmission, which means that they are likely to experience excessive slipping in and shifting of all forward gears.

Remanufactured or rebuilt 4r75e transmissions?

​

The 4r75e transmission features a few improvements, such as a more vital torque converter, a more robust ring gear, and a revised fluid pump. This transmission was first introduced in 2003 as a better alternative to 4r70. This lighter duty transmission is mostly found in 4.6L V-8 engines. The larger 5.4L V-8 is found with the 4r75, exclusively from 2004 on Ford Crown Victoria, Mercury Grand Marquis, and Lincoln Town Car, 2004-2008 F-150 Heritage, and 2006 Ford Expedition.

​

Reman transmissions indicate that some extra machine work has been done to a unit to bring it to the same standard as a new unit, while rebuilt transmissions imply replacing worn-out parts only. A sound 4r75e remanufactured transmission should have new mechanical tolerances set according to the factory specifications to ensure new-like quality and durability. This transmission is considered maintenance-free, with an electronic speed sensor and a greater integration between the transmission sensors and the engine's PCM.

Both remanufactured and rebuilt 4r75e transmission are good options for your Ford, depending on the nature of and cause of your transmission problems, but the remanufactured one is of better quality. Such factors as the make and model of your car, its value, and mileage covered affect the type of transmission replacement you have.
