Transmission doesn't want to move (slips)
in drive and reverse, but will go in low
pulling out and will shift manually through
the gears and go into drive and overdrive
when up to speed! Need help
As it will shift manually I suspect the TCM is starting to fail, a tranny shop can test the unit, or if you don't mind shifting it manually you can do that for a while, just don't over rev the engine, but eventually you will have to get checked and fixed. HTH
You can try adding some Lucas Transmission Stop Slip no promises that it will work but it worked for me when my trans started to slip. Like I said no promises but it is worth a try.
