A (TFT) transmission fluid temperature sensor is one of several sensors providing input to the (TCM) transmission control module. It’s located in the valve body or oil pan of the transmission or transaxle. The TCM uses this sensor to monitor the temperature of the transmission fluid.
How do you fix a transmission temperature sensor?
How do you change a transmission temperature sensor?
- Disconnect the battery.
- Remove the undercover under the transmission.
- Drain the radiator.
- Drain the ATF.
- Remove the bolts that secure the valve body cover and remove the cover.
- Use a small screwdriver to pry the connector from the oil temperature sensor.
How much does it cost to replace a transmission temperature sensor?
The average cost for transmission position sensor replacement is between $249 and $285. Labor costs are estimated between $134 and $170 while parts are priced at $115.
How do you check transmission temperature?
Install the scan tool, start the vehicle and look for the transmission temperature. The fluid temperature should be between the 185- and 194-degree marks with an idle of 600 to 800 rpms. Remove the bolts and clips from the front fender well on the driver’s side, and locate the transmission fill plug; remove it.
What does the transmission temperature sensor do?
The Transmission Fluid Temperature sensor measures the temperature of the transmission oil (AFT). Its primary function is to inhibit overdrive and converter clutch operation when cold.
How does a transmission temperature sensor work?
The TCM engages the TCC mechanically, connecting the input shaft to the engine to cool the fluid if it gets too hot. If the fluid temperature reaches a threshold set by the manufacturer; 300° F or so, the TCM sets a fault code and illuminates the MIL to inform the driver.
How can you tell if the transmission sensor is bad?
One of the most common signs of a bad speed sensor is abnormal automatic transmission operation. If the VSS is faulty, the transmission may exhibit symptoms such as delayed shifts, hard shifts, and limited gear operation.
Can you drive with a bad transmission range sensor?
This would cause the transmission to be in a different gear (controlled by the PCM) than the one selected by the driver using the shift lever. This could lead to unsafe operation of the vehicle and could likely become a traffic hazard.
How do you check transmission?
Pull out the dipstick, wipe it clean, replace it slowly, and then pull it back out. Check the fluid level—how high the fluid comes up on the dipstick—against the “full” and “low” or “fill” marks on the dipstick. The color of transmission fluid can tell you a lot about the health of your car’s transmission.
Why is there no transmission dipstick?
Automatic transmissions which use World Standard (WS) fluid are sealed and do not consume fluid. This eliminates the need for periodic fluid checking using a dipstick.

What do you do when the transmission temperature light comes on?
If you see this red light come on in your car, you should first pull over to allow your transmission to cool. If not, you could cause expensive transmission damage. Then, as soon as you can, bring your car in to have it serviced immediately.
