OUTPUT SPEED SENSOR DESCRIPTION The Input (1) and Output (2) Speed Sensors are two- OPERATION The Input Speed Sensor provides information on how fast the input shaft is rotating. As the teeth of the input clutch The Output Speed Sensor generates an AC signal in a similar fashion, though its coil is excited by rotation of the The TCM compares the input and output speed signals to determine the following: • Transmission gear ratio • Speed ratio error detection • CVI calculation The TCM also compares the input speed signal and the engine speed signal to determine the following: • Torque converter clutch slippage • Torque converter element speed ratio REMOVAL 1. Raise vehicle. 2. Place a suitable fluid catch pan under the transmis- sion. 3. Remove the wiring connector from the output speed sensor (2). NOTE: The speed sensor bolt has a sealing patch 4. Remove the bolt holding the output speed sensor to the transmission case. 5. Remove the output speed sensor (2) from the transmission case. 21 - 376 AUTOMATIC TRANSMISSION - 42RLE KJ |
