48RE Trans Service
I am in the midst of servicing AT on my '04 3500. This is the 2nd service I've performed but the 1st service at 70,000 mi I did not adjust the bands(just fluid & filter) as this was right after I purchased & did not know about band adjustment. I now have 104k & am trying to perform myself. I began adjusting the rear band & noticed my POS in/lb torque wrench is trashed & know I have over tightened it. My question is can I loosen back adjustment screw & start over with a good wrench of course? If so how will I know if correct or not when done? Or will it be obvious when driven? Any help/advice is GREATLY appreciated!!!

You don't really need a TQ wrench unless you are totally **** about it. The turns backed off are what matter more so than the set TQ. Good an snug, not tight, with a 3/8 drive ratchet is adequate to start with.
Back the rear band off 3 turns, front band 1 3/4 turns, those are what is important.

Thanks a bunch. Did as you said since couldn't find "lb TQ wrench that would set under 120 anyway. Replaced pan & filled up. Drove good. Def made a difference(hoping for the best). Shifts at what appears to be correct rpm/speed just does it A LOT faster...Going home to WVa for Christmas so if not I'll know then for sure
