How does a transmission temperature sensor work?
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. On some models, it also inhibits certain gears based on the temperature (too hot or too cold).
What is ATF temperature sensor?
Description. Thermometrics Transmission Fluid Temperature Sensor (TFT) measures the temperature of transmission fluid. It provides input to the control module to modify shift patterns for smoother shifting in automatic transmissions, and also provides over-temperature protection by locking the torque convertor.
What do I do if my 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.
Can throttle position sensor affect transmission shifting?
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems.
How do I fix error code P0713?
The most common repairs for a P0713 are as follows: Visual inspection of the transmission to determine leaks and fluid levels. If fluid is low, refill it, clear the code and monitor for it to return. Repair any obvious leaks, change fluid, clear the code and monitor for it to return.
What is a high transmission temperature?
#1 Cause of Failure The optimal temperature range for transmission fluid is 175 to 220 degrees. Above that, for every 20 degrees bad things happen, starting with formation of varnish at 240 degrees, followed by seals hardening, plates slipping, seals and clutches burn out, carbon is formed, and, ultimately, failure.
What causes a transmission temperature light to come on?
Simply this – your transmission is overheating. Hot transmissions give off an odor. Ideally, if your transmission overheats, your Transmission Temperature Light will come on. But keep in mind that warning lights are not infallible, so if you smell something out of the ordinarily (usually a sweet odor), pull over.
Where is the pressure sensor on a 545RFE?
Replacing a bad pressure sensor is relatively easy on the 545RFE transmission, as the pressure sensors are located in an easily accessible location on the side of the transmission. To replace it, you have to disconnect the battery, jack the vehicle up, remove the wiring, pop out the old sensor, pop in the new sensor, and reconnect the wiring.
Are there any problems with the 545RFE transmission?
Be sure to match the color-coded wires on your new solenoid to the wires on the old solenoid. The 545RFE transmission occasionally has problems with the pressure sensor, which is mounted on the side of the transmission. If it is just starting to go bad, you may notice that your transmission takes too long to get into gear.
What to do if your 545RFE is overheating?
To replace it, you have to disconnect the battery, jack the vehicle up, remove the wiring, pop out the old sensor, pop in the new sensor, and reconnect the wiring. If you are handy and have the right tools, you should be able to do this yourself. The 545FE is resistant to overheating, but it can happen.
