It makes the trans harsh all over the board,which is not necessary, hard on the planetaries and is really unnecessary abuse. The suggestion of turning up the pressure with the EPC solenoid is not the best route. You can build them bulletproof and still be very comfortable to live with day in and day out. You can tailor the line pressures in the tune to your desired feel,upshifting and downshifting,and not have that dreaded "bang" when you slide it into gear. Very hard on parts.īetter off to up the line pressures either via shift kit,or in the tune.
It will also cause "in gear" harsh shifting,meaning everytime you go from park to drive or neutral to reverse it will "BANG" into gear,a very unpleasant situation,and if you don't have your foot on the brake "hard" it will shove the car. It ups the pressure everywhere accross the board. Turning the little screw on the EPC solenoid does up the line pressure,but it causes other issues too. Also what we do is turn the EPC soleniod IN 1/2 turn to raise line psi, but be careful to not get carried away with the soleniod adj.Sonnax makes great tranny parts, I've used them on builds in the past. it is sonnax#77911-03k check it out on their web sight if it is even on there yet. I have the part # for sonnax's new servo that is ridiculous. If he has the corvette servo setup already and is STILL having 2nd gear issues (possible squak on band apply) going of his post.Then he will eat up his fresh trans too.He obviuosly needs more help keeping that band on and more line psi.
