OKAY , I will give a basic rundown.

2007 h3

new transmission installed

vibration upon acceleration from time to time, goes away at 2 -3 RPM's

When shifting from all wheel drive/4 high into 4high lock it no longer makes a sound as if engaging,
sounds and shifts normal from 4high lock to 4 low lock, and normal from 4 low lock to 4 high lock, no sound
from 4high lock back to 4 normal/all wheel drive. sometimes feels as if im constantly in 4wheel drive.

Another couple weeks go by and I get service stayb, traction control failed, reduced power and the codes
P060E and P0240

My question is, is their a relearn that needs to be done when the transfer case is pulled out and the transmission
is new? is their a accelerated pedel sensor or throttle body relearn that needs to be done? I have unplugged and
cleaned the throttle body.
and also had hand on TCCM while having the 4wheel drives gone thru and it feels to be engaging except going into
4 high lock.

If you have the 6L80 tranny, you have to get the PCM flashed.

If the OP replaced his trans with a stock one, then his 07 H3 has a 4l60e. It doesnt require or have any recalibration/reflashing available. The trans controller is a seperate piece from the trans itself (unlike the 6 spd)

Code PO240 or P0420?

When you state that you feel like it's always in four wheel drive, what do you mean? Hummers do have permanent 4WD. What symptoms are you seeing or feeling that make you think the operation isn't normal?
