    Kevin, any word on deleting AFM in the 2021 GMs yet? Was pretty cool they don’t put trans thermostats in the newest gens.

    And if AFM couldn’t get any better, GM increased AFM to all 8 cylinders starting with 2022 models

    Just wanted to give an update, had A2Z delete the trans stat on my 2014 Silverado and do a trans service at the same time about 2 weeks ago. Previously when pulling the boat, the trans temp was well into the 240’s. Pulled it today and never saw over 195. Had Kevin previously delete the AFM, and if anything, fuel mileage seems to be slightly better. Your choice.

    Took my 2015 Sierra in to have the AFM/Trans Thermostat deleted last week...oil change and tires rotated too.

    Looks like my fuel mileage is down a bit, but the truck drives a lot better. I hated feeling that AFM kick in.

    Walked in at 3:30 and left at 4:15, KRT runs a tight ship!
