Ok i have a Dodge neon 02 i took the tranny to replace the main rear seal when i put everything back in and put the tranny bolts on snug i can turn over the engine and the tranny and like up the torque convert and put the bolts in the fly wheel and i can turn it nice and smooth when i start to tighten the bolts on the tranny it and try to turn it it sounds like its scraping and once its all tight it wont turn at all. even when i untightened all the bolts it wont turn not sure what is wrong with it HELP PLEASE!! also trying to find a install guide for the tranny.

 

sounds like the torque converter is not lined up. I had the same issue when I replaced my tranny, its a bitch to line up. I thought I had it about three times but didn't, try pulling it and taking the converter out and realigning it.

 

+1 Been there done that after completely reassembling the front end.
