well my 4l60e has been slipping and now it has seemed to lock up. so preparing for the future of this truck I'm going to go 4l80 with it. what torque convertor would you guys recommend? For now its pretty much stock l31. it does have a true dual exhaust with high flow cats. any help would be greatfull.
