    2016 Crew Cab Trans Tune?

    My truck is currently tuned with Autocal.

    My mods are Suncoast cat 3 68, S&B CAI, and turbo back exhaust. Full diet

    I’m having a harsh shift from 3 to 4.

    Usually around 30mph.

    Me and my current tuner have tried a couple of things, but it never really got any better.

    I’m not against going full-out MM3 to handle this, but I’m curious if anyone here has dealt with something similar.

    What's the line pressure on the trans?

    Describe hard shift, like it shifts hard?

    Or is it a shift flare from 3rd to 4th?

    It all depends on who is doing the brains on the motor.

    It’s a pretty firm 3-4 shift.

    I don’t know the line pressure.

    To help out a bit more, how many miles on the trans?

    I'll be the first to tell you; Transmissions are not my strong points.

    Going to a reputable shop, have them scan the trans to look at codes that may not be seen and the index numbers.
