Problem Information

1st gear drop out
All the time
Fwd clutch drum
Truck came in hard cut seal on forward clutch drum and drum broken on snap ring grove. Also e clip on end of o/d servo broken. Everything else in perfect condition. Replaced all gaskets seals, friction sand both bands. Cleaned vb and vac tested all common areas. Found no probs
None

Problem

Truck was driven on 2 separate test drives and worked perfect. Went to take it on a 3rd just for fun and truck has now started this. Take of from a start in 1st. Then it brutalizes for a sec the back into gear. I some times does this 2 or three times in a row. Line pressure tests and epc pressures perfect even while it it doing this. Forward clutch pressure is messed up thou while it acts up. It will be at 200 psi when in gear then drops to 50 while it neutrals. The back up to 200 when re engages. Removed vb again and have found no probs. no codes present and all data looks normal. Looking for any ideas
