If I install a transgo shift kit, both billet servos, and the aluminum accumulator, how will my truck shift with a stock tune?

 

Bark!!!

 

It's gonna hit at WOT 1-2 hard, 2-3 is gonna be TqMgt'd badly. You can't get a good idea on the 3-4 due to that ~97mph limiter and soft TCC lockup.

Your low throttle shifts are going to be much firmer in all gears (obviously) and you shouldn't notice too much weirdness down low. My 2-3 shift was effected the most. I drove on a stock tune w/ TransGo + billets for 3-4 months I believe it was.
