I have a 2000 silverado 1500 that I just changed the auto trans and torque converter, apon completing the installation wanted to try it. Truck started fine but when i put it in gear the truck does no move but I can hear the engine slightly idle down when it goes into gear. I pulled the rear drive shaft off and checked to see if the transfer case tail shaft was spinning in gear which it is. Everything seems to be working but not transfering enough power to spin the rear axle. As anyone had an issue like this or know some possible troubleshooting tips to help
