I got a 67 camaro w/ an LS1 and 4l60E. I just put the tranny in for the first time and when i put it up on the lift and put in any gear i get nothing. The wheels are free and loose (brakes aren't locked). I triple checked all wiring and it's all plugged in correctly. I have tried R,D,3,2,1 and all i've ever gotten is a little tire rotation in reverse (very little). It has plenty of fluid. I am not very familiar w/ this transmission and I have no clue what is happening. Could it be a bad torque convertor clutch?

p.s. - the transmission is a used tranny w/ 80,000 miles

Thanks for all the help.
