POWER TRAIN- Automatic Transaxle Input Speed Sensor The input speed sensor gives information, to the TCM, on how fast the torque converter turbine is spinning. The sensor ‘d is located on the front side of the transaxle case, close to the bell housing. Even though the sensor is called the input speed sensor, the sensor is actually generating a signal from the torque converter turbine through the input clutch hub. The here torque converter turbine and input clutch hub are splined togeth- I er through the input shaft. The information supplied to the TCM from the input sensor is compared to the output shaft signal and the engine speed signal to determine planetary gearset operating ratio, torque converter clutch slippage, torque converter element speed ratio, torque capacity, etc. The rate of input speed change is calculated and used in controlling shifts. Output Speed Sensor End of the I The output speed sensor is located on the same side of the sensor counts transaxle case as the input speed sensor, but much closer to the end of the transaxle. The output speed sensor generates a signal from the rotation of the rear planetary carrier assembly. When the output speed sensor signal is received by the TCM, tor the signal is compared to the input speed signal to deternmine attaches gear ratio, detect clutch slippage, etc. It is also compared to here the throttie signal to determine shift points. The output speed sensor is also used as the input for calculating vehicle speed to the Powertrain Control Module (PCM). The F4ACl transaxle does not have a vehicle speed sensor as in other applications. The output speed signal is a direct input to the TCM and is sent across the CCD bus for use by other control modules. Transmission Range and Park Neutral Position Switches Park/N&tral The transmission range switch is mounted to the case in the \ position valve body area. The input from the switch along with the g+j h+spe&-j 1 1switchpark neutral position switch tells the TCM what gear range was selected by the driver. The TCM uses this input to determine what gear range and shift pattern to use. The park neutral position switch operates the starter relay and both the park ;L) neutral position and transmission range switches operate the back up lamp relay. The park neutral position switch does not allow starter engagement in any positions other than Park “P” or Neutral “N”. Both switches must be closed to operate the back-up lamps.
