Do you mean it doesn't go into 4th gear and the torque converter clutch doesn't engage? Does it not start in neutral and in park??? It should. Brake switch can prevent TCC engagement.

zipper Posted April 13, 2011 Report Share Posted April 13, 2011 You don't have a 4T60E, you have a 4T65E. Read this: http://www.tripleedgeperformance.com/No_4th_Gear.html It's a common problem with these tranny's. Quote Link to comment Share on other sites More sharing options...
