Transmission Temperature Sensor/Switch: Service and Repair

Torqshift - Automatic Transaxle/Transmission

Transmission Fluid Temperature (TFT) Sensor

Removal
1. Remove the transmission fluid pan gasket and filter.
2. Disconnect the transmission fluid temperature (TFT) sensor electrical connector.





3. Press the tab, rotate the sensor counterclockwise and pull out.





4. Inspect the O-ring. If the O-ring is damaged install a new TFT sensor.

Installation

High Efficiency Sump Filter (HESF)

CAUTION: The remote filter and the previous design sump filter are both replaced by a high efficiency sump filter (HESF), which requires a wider and deeper bottom pan. Always pair the sump filter with the correct bottom pan design, to avoid cavitation, filter cracking and transmission damage.





1. Lubricate and install a new TFT sensor. Make sure to slightly rotate the sensor to lock it in place.





2. Connect the TFT sensor electrical connector.





3. Install the transmission fluid filter, pan gasket and pan.

4. CAUTION: The use of any other transmission fluid than specified can result in the transmission failing to operate in a normal manner or transmission failure.

Fill the transmission.
^ Add 7.0 L (7.5 qt) of clean transmission fluid to the transmission through the transmission fluid filler tube.
5. Start the engine. Move the transmission range selector lever through all the gear ranges, checking for engagements.
6. With the vehicle in NEUTRAL, engine running and the transmission at normal operating temperature 66-77° C (150-170° F), check and adjust the transmission fluid level and check for any leaks. If transmission fluid is needed, add transmission fluid in increments of 0.24L (0.5 pt) until the correct level is achieved (transmission fluid should be in the hot range cross-hatched area of the transmission fluid level indicator).
