I was given a 1994 Honda accord that has a awesome body and the interior is awesome. But the the auto transmission is out. It was replaced with a used auto transmission but when it was put in it keeps dropping in low gear. It has a lock cyclinder beside the shifter and even thou the trans was changed out you still have to use the key in that lock cyclinder to get it out of gear. CAN SOMEONE PLEASE HELP ME WITH THIS ISSUE ???
