I have recently installed an engine(350 vortec)and transmission (350turbo) in my 1973 chevelle project. My problem is when I put the car in drive it will only move (forward) if I press the throttle.It will not go in reverse (even when I give it throttle). I put the car on jack stands same results (tires will not move forward unless you give it the gas) but will not go in reverse. I put the car in neutral (still off the ground ) and I cannot turn the driveshaft by hand . I'm hoping this is something simple I'm over looking. I have checked the convertor its in correctly. I ran new 3/8 transmission lines recently filled the transmission with fluid and checked the fluid levels . Unfortunaty I do not know the history of the transmission as it came with the body. Am I overlooking something ? The rear tires do spin freely so its not the rear. Shouldn't I be able to turn the driveshaft in neutral by hand with the rear off the ground? Please any help will be greatly appreciated.
