4L60 or 5 speed? I have a 1992 Gmc Sonoma Gt with a 4L60 behind a 4.3 Vortec. I've heard a lot of bad things about the 4L60 and seem to be experiencing one now. 1-2 shift chirps them tires or scoots the hind end side ways depending on my current driving surface and throtle amount. What all do I need to change out the auto for a stick? I know I'll need a flywheel, clutch, pedal, hydo clutch cylinder. Will I need a new bell housing or crossmember? Which model trans would be best?
