About this transmission
Transmission general data
The 5R55E is an automatic gearbox produced by Ford. It is the five-speed automatic transmission, which was widely applied in both two and all-wheel drive cars. This transmission found application in various Ford models (such as Lincoln and Mercury).
Regarding the mechanical part, the 5R55E is similar to the 4-speed 4R55E. The 5R55E has the adaptive shift control and directional high energy frictions. It was the 1-st five-speed electronically-controlled gearbox in an American car.
Common issues:
1)Malfunction of solenoids – this transmission
employs solenoids to control many of its functions, including the gear shifting
process and operation of the torque converter lock-up. The simplest and method
of testing solenoids is to use the ohm meter, which measures solenoids
resistance.
2)High chance of overheating: like any other automatic gearbox, the 5R55E is subject to overheating, especially if it is exposed to severe operation conditions. Overheating frequently leads to the transmission failure, therefore transmission repair specialists often recommend installing transmission coolers, which help to cool down the transmission.
