Transmission Fluid Temperature (TFT) Sensor: Installation
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The remote filter and the previous design sump filter are both replaced by a high-efficiency sump filter, 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.

- Lightly lubricate the O-ring with automatic transmission fluid and install a new TFT sensor. Make sure to slightly rotate the sensor to lock it in place.
- Connect the TFT sensor connector.
- Install the transmission fluid filter, pan gasket and pan. For additional information, refer to Fluid Pan, Gasket and Filter .
- Fill the transmission.
- Add 7.0L (7.5 qt) of transmission fluid to the transmission through the transmission fluid filler tube.
- Start the engine. Move the selector lever through all the gear ranges, checking for engagements.
- 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).
NOTE:
The use of any other transmission fluid than specified can result in the transmission failing to operate in a normal manner or transmission failure.
