Ok, my line pressure is "boosted" on my 98 Z28. I have a stock 70K mile 4l60e with a SS4000 Yank and a trans-go HD2 shift kit. What should my line pressure be at with these mods? I dont want to kill my tranny in another 6mths again. Thanks for looking

Bringing this one up
I killed my 4l60e w/hd2 and boost line pressrure w/hptuners because the tab on the 2nd gear band bent. I'm putting that trans back in and wondering what max tune line pressure to run myself

If you've got a shift kit or a built tranny, put your line pressures to stock in the tune.

My guy at GM Powertrain says 220 psi max.

My 60s have been living great with the tune I am currently running. Although when swapping from a stock trans to a built unit the low speed shifts were too hard but a slight adjustment in the upshift modifier table and its shifting like a dream.
