I have an 88 f250 with the 460 and auto tranny. How much is the tranny and transfer case worth? It works great

 

It's a C6 that will only fit behind a 460. Take what you can get for them, it won't be much.

 

I sold a BB 4wd C6 for $80 that worked good with 115k miles, and I sold an EFI 460 that ran perfectly with 150k miles for $200. Sometimes you get lucky, other times you will have an item listed for months with no replies.
