I was curious how much you can safely increase line pressure on a 4l60? I'm looking to increase mine some but dont want to grenade my trans.

If you mean by software, don't worry. The mechanical
line pressure max is what you see at WOT anyway (if
you haven't buggered air mass calculation).

I've been running around with a more aggressive force
motor table for many many years and no prob.

Now if you're talking about dropping the pan and
turning a screw, there you probably want some more
guidance.

 

Yeah I was going to use efi live to do it. I just heard you need to be careful with how much you give
