4l80e soft 2-3 shift slips in 3rd I have a built 4l80e with Jake's d1 vb. Last year it worked flawless in a turbo ls 79 firebird well we switched to non lockup 9.5 ptc converter and did trans go non lockup kit in the pump. Car runs excellent first and second gear are great but the 2-3 shift is soft and slips in 3rd. Boost drops in third and car stops pulling hard. Line pressure checks out good about 180 in every forward gear and about 270 in reverse. Any ideas or tips on why it's doing this?
