[QUOTE="Nasty02Avalanche, post: 3397, member: 414"] The Tow / Haul inop problem is a known problem. Soldering the wire will not solve the problem, the harness is already compromised. Just think about how many times it has been shifted from park to drive to reverse to park. The repair involves installing a new shift lever and taking apart the cover around the column. A more simple repair is to take apart the column, take the wire off the plug, solder a simple two conductor wire to a switch / mounted beneath the dash. When you want to haul something, just click the switch one time and it will activate the tow haul mode. A push button momentary switch would work best. Just do not leave it switched on, or you will have transmission problems somewhere down the road. The switch - if just toggled momentarily will automatically reset when you shut off the vehicle.
