how far can i go?????????????? we backed the screw off 2 and 2/3 turns and i really can't tell much of a differance. i remember reading some where how much psi each turn was but i can't find it. anyone know what i am talking about?

 

I did mine too and it seemed like it was backed out all the way because it was just loose and you could feel it click back in when unscrewing it, and my trans shifts harder now I think, but not very much different.

 

Turn it counter clockwise to increase line pressure and 1 turn = 3 PSI according to this.
