01 LB7 168,000 on what i believe is a stock tranny. Now when im going around 33mph the truck will not shift unless i left off the throttle at just the right moment. If i miss the shift the dash lights come on and it throws a code and it throws it in limp mode. Once i get it to shift it does just fine..my question is the tranny done for? anything i can do to help prolong its life? lol not ready to break the bank yet!

What code is it throwing? P0700 or similar? Sounds like your tranny is on its way out.. Nothing to do now but start saving for a built and put the tuning back to stock and baby it if you want it to last a while

Sounds like a solenoid issue, what are the codes?

Clutches are done and material in the VB causing shift failure.
