In Reply to: C4 tranny improvement...harder shifts for pocket change! posted by David Blodgett on December 06, 1998 at 00:01:46:
: Going through some books in the local library, I found an article on modifying a C4 for harder, firmer shifts that will cost only a few dollars. It is done by increasing fluid pressure from 65-70psi to in excess of 100psi. All you need is a new gasket, filter, and a small cotter pin. The modifications can be done WITHOUT removing the trans from the car ( a huge plus ). I'm going to scan the article as soon as I can check out the book again. If you would like a copy of the article, send me an email.
