My Contour V6 ATX has problem since last year. The code is P0741, TCC stay off. I replaced VB, Solenoid, TC since then, but the problem still there, and becomes even worse now. I check the line pressure, 65PSI for P/N/R and 45PSI for D/2/1. Everything seems normal. I am so frustrated now. Any body can give a clue?
