I took my car to a friend who owns a trans shop and he checked out the slipping problem in 2-3. He told me the accumilator spring was bad and whoever put in the shift kit (AAMCO by previous owner) put most of the springs in backwards and a couple were destroyed. He said everything else except the servo was fine it would have been good for moms car but not the T/A so he put a vette servo in. $80 and it shifts great I can burn 2nd and even catch 3rd with my little 5.0.
