zx7 Posted January 13, 2008 Report Share Posted January 13, 2008 I have a 96 Cutlass Supreme. Transmission went out and I had a shade tree replace it. I am not sure what the trans he put in came from but i dont think it has OD. The problem i an having is when i hit 70mph the car surges and the RPMs bounces a little. I put my foot on the brake just a little and it drives fine. while riding the brake. What does that me and what should i be doing next?

ManicMechanic Posted January 13, 2008 Report Share Posted January 13, 2008 Sounds like TCC to me... Quote Link to comment Share on other sites More sharing options...
RangeStang Posted January 13, 2008 Report Share Posted January 13, 2008 Yep! my 92 has the same problem at about 50mph it is TCC that is causing it. Quote Link to comment Share on other sites More sharing options...

ManicMechanic Posted January 13, 2008 Report Share Posted January 13, 2008 When I got my van, it did the same thing. Changed tranny fluid, filter and added a cooler...Not a chug since. Quote Link to comment Share on other sites More sharing options...
ismellrealbad Posted January 13, 2008 Report Share Posted January 13, 2008 yeah its fine when you hit the brake because when you do that its disengaging the tcc Quote Link to comment Share on other sites More sharing options...
