I believe the TCM was replaced in the rebuilt unit, but it sounds like the solenoids were not. The computer is now throwing a solenoid error code after some miles. I have new solenoids in hand, just have to get around to replacing them to see if that solves the issue.

Its not unlocking the torque convertor when you take your foot off the gas, its when you just lift a little to stay at 55-60, instead of continuing to accelerate.

I just dropped a rebuilt transmission from Rockauto into my 2000 Suburban and I am having two problems with the new unit. I was wondering if anyone here could point me in the right direction for troubleshooting. 1. The gear indicators on the tree on are not lining up with the transmission. The indicator usually skips N, and doesn't always indicate park. I have messed with the shift cable adjustment quite a but and it doesn't seem to make much of a difference. At the moment I am thinking the problem may be the Neutral\Park Sensor on the side of the tranny? The tranny didn't come with a new one, bit the old one wasn't having any indicator issues before replacement either. 2. The truck doesn't want to stay in overdrive unless you are heavy on the gas. As soon as you let your foot off the gas once you get to speed (55) the tranny will drop to 3, or maybe the torque converter is unlocking, it will be at about 2200rpm at 55mph. I am wondering if this could be a line pressure issue? There is a spot to adjust line pressure on these correct?
