Where is the transmission heat sensor?
Where is the transmission heat sensor?
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.
What should I do when my Allison Transmission shifts?
So the transmission shifts– for example 5-4-5-4-5-4. This builds heat in any transmission. Easy solution on any transmission is to dowhshift so that the transmission stays in the lower gear until the grade eases and you can return to a higher gear. With your Allison, use the “down arrow” to select the lower gear when this occurs.
Why does the Allison Transmission generate more heat?
Because the torque converter in your Allison locks up at higher RPM’s in 2nd”, and is locked in 3rd, 4th, 5th and 6th gear there is not a lot of heat buildup due to the converter slippage except in very slow stop and start driving. The transmission will generate more heat is when stopped for a long period with the transmission in Drive.
What should the sump temp be on an Allison Transmission?
Also, Allison data says the sump temp.( which can be seen from a service tool) should be 200 degree F typical and max 250 degree F. To me your 215 degree converter out should provide approximately the typical 200 degree sump desired.
Where is the transmission temperature sensor located?
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.
What is transmission temp normal?
The ideal temperature for your transmission is 200 degrees. For every 20 degrees past 200, the lifespan of your transmission is reduced by a factor of 2.
What is a transmission fluid sensor?
The transmission fluid temperature sensor (TFT) sensor produces a signal that is used by the powertrain control module (PCM) to determine shift points, line pressure and torque converter clutch (TCC) control. The sensor is often located in the transmission oil pan.
