band is slipping.
about 10 different causes for that.
9 in the valve body...1 in the clearance of the band.
if the clearance is greater than .125...weld .070 onto the band pin tip and put it back together...if there's any band left that you haven't smoked...it'll work again.
Also do a pressure test just to make sure you don't have an issue there

Morning was fine...last night was a LATE one. Driving until about 1am.
Let's neglect my first post...talking about 60 vs an 80...woah that's a rookie move!
Slipping in 2nd on an 80e is likely one of the following
A. center support bolt loose. Leaking all pressure away.
B. you don't have enough fluid in the trans. Unfortuneately that happens WAY too often...guys run 80s low and have it slip 2nd because the fluid isn't making it to the pump. First is usually OK because they're statically applied before you're moving.

For more info I originally noticed it slipping getting on the interstate in over drive. Then tried it again floored in drive and it seemed to be holding. I took it to the track and logged on hp tuners. I could definitely feel it slipping put would stop about halfway through the gear. And 3rd held no problem. Thanks for your help.
