Does anyone remember how the pressure scales up as the set screw is turned in? IIRC its 1/4 turn = an additional 30 psi but my memory is terrible. I'm contemplating giving the 60E in the 99 a 20-30 psi increase when I change the fluid and filter. I'm not really after a firmer shift, just wanting a little more holding power on the clutches. I have zero faith in the 3-4 clutch pack on this thing.

 

A 1/4 turn will give a more positive shift not to sure about how much more pressure though, I wouldn't go crazy with it either.

 

Super old bump but I figure it would be better to bump up then to repost.

I plan on doing an filter change on my "built" 4l65e that shifts a bit firmer than I would like and I've already adjusted the shift pressures back to stock with HPtuners and I assume the screw has been adjusted.

I'd like to adjust it back down but don't know how much to.

help!

 

anyone?
