Thread: Transmission Temperature ECU Input

  1. #161

    Default

    Trying to setup an OE GM 2-wire temp sensor that is already in place on the transmission (also same OE sensor on the differential). I have it configured as a GM LSx CTS, which clearly is not correct, as it reads 60°F too high compared to ambient temps. I can setup as a 'Custom Therm', but can't find any settings that correlate to the GM 2-wire. (Note: OE transmission temp sensor on a '01 ZO6 T56 transmission & differential.) Any guidance?

    You'll need to ascertain the sensor calibration data (or measure hot & cold temps with an Ohmmeter), or use sensors with known calibration data.

    I've searched, but no such luck. A Holley CTS temp top range is too low at 275°F (hopefully never gets that hot, but possible on track). Sounds like an Auto Meter 2259 sensor and connect the single pinned wire would be the best way to go. Thanks!

    You're welcome. There's three different temperature sensors to choose from (LINK).
