So I posted before about my tranny losing power around 35mph when it's cold. After the transmission is warmed up, it'll drive just fine. Now I realised when it's cold, I can up shift with the tapshift and it'll drive just fine. I just put it back into drive once I'm ready to set my cruise control. Do I need a rebuild or can I get away with solenoids and a shift kit? People have said rebuild and others have said a shift kit and solenoids. Anyone help? 2004 comp g.
