I'm poking at tuning the 6R80 in my swap. I've got the shifts pretty firm by upping the line pressure on the shifts, but am curious, does anyone know the MAXIMUM you should run on these transmissions? The box allows up to 500 PSI to be entered, which from the way I'm shifting it now would seem like it has a lot of growing room for holding power on the up shifts.
I'm currently at 250 psi, stock was 150. I pretty much got it to the point where it barks the tires on the 1-2 and has a solid hit on the 2-3 and 3-4 and stopped. I do plan on adding more power later on, so I'm just curious as to how high the PSI can be set, and not do any internal damage or if possibly you aren't even supposed to command over XX amount of PSI to begin with.
