Where does the transmission temperature sensor is located?
The sensor is usually located within the transmission, and it is able to detect when the fluid temperature exceeds a certain threshold.
Why does the Transmission Temp Sensor be important?
The transmission temp sensor is an important component of the transmission system because it helps to regulate the temperature of the transmission fluid.
It monitors the temperature of the transmission fluid and sends a signal to the vehicle’s computer or transmission control unit so that it can adjust the transmission fluid temperature accordingly.
This helps to ensure that the transmission fluid is operating at its optimal temperature for safe and efficient operation.
How does the transmission temperature sensor work?
The transmission temperature sensor is a temperature sensor that is used to measure the temperature of the automatic transmission fluid (ATF). It is usually installed in the transmission pan and measures the temperature of the ATF as it passes through the transmission.
The sensor then sends a signal to the vehicle’s computer to alert the driver when the temperature of the ATF is too high. This helps to prevent transmission damage from overheating.
It can also be used to adjust the transmission shifts to help optimize fuel economy. The ATF temperature should be monitored regularly to ensure that it is not too high, which can cause damage to the transmission.
How To Install Transmission Temp Sensor?
- Start by locating the transmission temperature sensor, which is typically found on the transmission pan.
- Using a wrench, loosen and remove the existing temperature sensor.
- Take the new transmission temperature sensor and screw it into the transmission pan.
- Tighten the temperature sensor with the wrench.
- Connect the wiring harness to the sensor.
- Secure the wiring harness with the mounting clips.
- Start the engine and check the temperature gauge on the dashboard to ensure the sensor is working properly.
- The ground of the vehicle must be connected to both the temperature sensor and the transmission temperature gauge (chassis or earth).
- Electrical tape must be used to insulate unused wires in order to prevent accidental electrical connections.
- All electrical connections must be made using soldering or crimping on electrical connectors.
- Observe good electrical operating procedures. For more information, see the table and diagrams below.
Transmission temp sensor symptoms
The coolant temperature sensor may be broken if you notice that your engine overheats. The coolant temperature switch may occasionally malfunction and begin permanently transmitting hot signals. As a result, the computer incorrectly counterbalances the signal, which leads to the engine misfiring or overheating.
- Check Engine Light: The check engine light on your dashboard may indicate a problem with the transmission temperature sensor.
- Overheating: If the transmission temperature sensor is faulty, then your transmission can overheat, leading to problems such as sluggish shifting or transmission slippage.
- Poor Fuel Economy: A faulty transmission temperature sensor can also cause your vehicle to burn more fuel than normal, leading to poor fuel economy.
- Erratic Shifting: If the transmission temperature sensor is not working properly, then your transmission may shift erratically or slip out of gear.
- Leaks: A faulty transmission temperature sensor can cause the seals in your transmission to fail, leading to fluid leaks.
- Noisy Transmission: If your transmission temperature sensor is not working properly, then you may hear strange noises coming from your transmission.
- Loss of Power: A faulty transmission temperature sensor can cause your engine to lose power, leading to a decrease in performance.
Can you drive with a Transmission temp sensor?
No is the simple reply to this query. Even though your car might technically be able to move and get you from point A to point B, you shouldn’t drive it. Especially if the engine is overheating, this could cause more damage to your car.
The sensor is designed to measure the temperature of the transmission fluid and alert the driver of any potential problems that could arise from a too-high or too low temperature.
This is especially important for automatic transmissions, as the transmission fluid is essential for the proper functioning of the transmission system.
How much cost and time does it takes to replace/ repair the Transmission temp sensor?
The cost and time to replace or repair a transmission temp sensor will depend on the make and model of your vehicle. Generally, the cost to replace the sensor can range from $150 to $400, while repair can range from $100 to $300.
The time required to replace or repair the sensor can range from 1 to 3 hours.

Can temperature sensor affect transmission?
Yes, a broken coolant temperature sensor can turn on the MIL and make the engine run lean or rich. The torque converter may not lock up or the transmission may shift incorrectly.
