AOD rebuild
tsmart,
When I had my AOD rebuilt back in 2011, it cost me $1,100 for the rebuild. I got the transmission for free, came with the donor car for my 5.0L EFI swap. $50 is reasonable for something you will have to spend over 1K to fix.
Did you get your transfer case adapter already for the AOD? Advance Adapters is the place to be for the adapters.
Good luck.
v/r,
