Hey guys, I have a 01, 1500 QC with the 360 and an auto tranny. I was having problems with the trans, whenever it would shift from 1st to 2nd it felt like it wanted to shift back down. Now this didn't happen all the time, when I would get on it about half throttle or so it would go just fine, shifts are firm and snappy. Sooooo I took it into the shop they thought it might be a misfire at low RPM, hooked up the computer to it and no misfires. Made a few calls and everyone said it was the governer pressure sensor and solenoid in the trans. OK, then my battery goes down hill so I replace it. Now the weird part, the trans has been fine every since. WHAT THE #%*!. I hope someone can help. I would hate to spend the $500-$600 on something that works fine. Thanks Guys

 

From what I have read low voltage or dirty or loose connections can cause all sorts of problems.
