i have a 66 Powerglide, out of a 6 cyl. Nova, that i recently rebuilt myself. i bought the manual and followed the instructions to the best of my ability. when we put it in my car, lifted the rear off the ground, added fluid, and gave the engine some throttle the wheels wouldn't even move. in fact i can push the car, like it's in neutral, in every position except for park. if it matters i do not have a vaccume line running from the carb to the modulator. i'm sort of at a loss. the manual says that it could be low fluid and i was thinking that maybe the fluid hasn's gotten all the way through the trany yet but i really don't know. if anyone knows waht the problem could be please let me know. the car has been sitting now since the beginning of September and i am eager to get it back on the road. your help would be greatly appreciated.
