how many sensors on 5R55E trans

[spanky50]

i have a 97 ranger 4x4 4.0 : i have my trans out and bought one from the parts store the one they got me only has 2 sensors on it. the one i took out has 3 on it. I believe mine is a 5r55e any ideas.

5R55E From the manual;


Electronic System Description

Shift scheduling, timing and feel (line pressure), as well as torque converter clutch (TCC) operation in the 5R55E is controlled electronically by the powertrain control module (PCM).

Input signals from various engine sensors give the PCM information about the engine's operating state. Other inputs are based on driver demands, such as the accelerator pedal position, which is monitored by the PCM using the throttle position (TP) sensor. Inputs are also supplied by the transmission itself. The turbine shaft speed (TSS) sensor, the output shaft speed (OSS) sensor and the transmission fluid temperature (TFT) sensor supply information to the PCM.



Using these input signals, the PCM can determine when the time and conditions are right for a shift or TCC application. The PCM controls six solenoids: four ON/OFF solenoids for upshifts, downshifts, and coast clutch application, one for pulse-width modulated control of the torque converter clutch and one for electronic line pressure control.

Looks like the 5R55E has 3 sensors, the 4R44E has two sensors according to the description above.
