[QUOTE="Nasty02Avalanche, post: 3483, member: 414"] The tow / haul switch holds the transmission in gear longer and shifts faster than the stock configuration. It also uses some dynamic braking, applies a lower gear while freewheeling downhill and applying the brake., My guess is that you were manually shifting the transmission, which causes the wire to the switch to fail and eventually the transmission will fail when the Shell breaks. There is whole web pages devoted to the shell problems and cures. The weaker - standard shell in a 02 Chevy would crack longitudinally. The heavier stainless steel shell would crack around the weld where the shell was attached to the hub spline. Some failures would even take the splines off the shaft. [/QUOTE]
