I had the transgo kit in my 95gt and I never had problem with it it up and down shifts were great , it shifted like stock but harder and I had it in the car for over 1 1/2 yrs ( I would check the trans fuild when warn after driving 2-3 miles and put the car in park or neutral and check the level) if you already did that then it could have install wrong. or the trans might need a rebuild , maybe the tv cable not right (not the one to in your house).
