I have a 01 auto. I recently put 3.42 gears in the rearend and while it was apart I put a 3200 stall to handle more power later. The car was dynoed at 347 at the rear wheels right now. My problem is I drive alot at speeds under 40 mph. I work on Hill AFB and there is a hill I go up to get to work. The car is in drive and its pulling about 1200 rpm and the torque convert is locked up. The car will on sometimes start to bog and shutter like the torque converter can't decide weather it wants to stay locked or unlock. If I give it a burst of throtttle it goes away. Do you think I need to increase trans pressure? Hope this makes sence. Thanks in advance Laurence.

Did you reprogram the PCM after installing the 3.42 differential?
