Replacing the trans. March 14, 2005, 04:28:03 PM Ok, my reverse is toast. Now heres the deal, I have an AOD out of an '84 LTD that had the police package. Now I'm curious if I can use that trans. The other thing I'm wondering about is the number on the bell housing. My bird has 52 stamped on it and one off the LTD has 54, I was just wondering what those stood for.
