    Hello,

    As I read a lot about overheated automatic transmissions in cars from the USA, I decided to install an oil temperature gauge in my 4l60e gearbox. My question, where will the measurement be the most reliable? I wanted to mount it on the cable that goes from the box to the oil cooler, but I have a problem finding a suitable T-piece that I could install without cutting the wires.
    So the second idea is installation in an oil pan, but does it make sense? The oil in the bowl is probably lower temperature than in the box itself? What do you think about it?

    best regards
    Paul

    Whenever you install the sensor, you will have to get used to its indications.
    Under normal driving conditions, it will show some reasonably stable temperature.
    When you tread, you will see it higher than in a deep fryer ;-)

    Oil temperature sensors in automatic transmissions are mounted either on the valve plate or in the plate itself.

    Thanks for the info. Unfortunately, I do not have such a sensor at the factory. I think so in the oil pan will not be bad either. Maybe the indications will be a little lower but I will have some opinion.

    best regards

    Oh gosh, actually. But what is he doing there? Ecu needs some information about the temperature of the box? Maybe there is an overheating warning or something ... interesting.

    It is not the ECU that needs information about the box temperature, but the TCM. If the oil temperature rises significantly, the sensor will register it, send it to TCM and the transmission will go into emergency mode.

    Thanks. I guess I discovered my problems with occasional jerks from 1-2 and 3-4, especially at higher revs. There are some communication errors with TCM.

Topic summary

The discussion centers around the installation of an oil temperature sensor in a Chevrolet 4L60E automatic transmission. The user seeks advice on the most reliable location for the sensor, considering options such as the oil cooler line and the oil pan. Responses indicate that while the oil pan may provide lower temperature readings, it can still be a viable option for monitoring. Additionally, it is noted that the factory setup may include a sensor on the valve plate, which communicates with the Transmission Control Module (TCM) to manage overheating issues. The user also mentions experiencing transmission jerks, potentially linked to communication errors with the TCM.
