    Cruise control not working 18 Colorado v6 8l45

    Hey guys,

    2018 Chevy Colorado v6, unlocked TCM, regeared from3.42 to 4.56 diffs, and running 35 inch tires. Stock was 30.5

    Truck was tuned by peitz performance and outside of the shifts are a little hard when daily driving (they are great when driving fast in the high desert), the cruise control stopped working. Everything else is fine.

    I didn?t realize it at first, just thought I had not figured out the switches yet on the steering wheel. But I am hearing others report now that with new gears their cruise control doesn?t work.

    Tire diameter has been programmed in as well as the gear ratio.

    Anything I should look for in the TCM or ecu programming to get it to work again?

    It’s the abs/traction control speed sensor that is not currently available to be adjusted. So when tires and/or gears are adjusted then it doesn’t match up and issues occur. Support ticket in, they are looking into adding the feature.
