So the C4 lost 3rd and Reverse on the way home from the Car Craft Nationals last summer and the 289 will need to be replaced or rebuilt in the near future. I found a 92 Lincoln Mark VIII with the 5.0 HO and AOD. If I kill two birds with one stone, what modifications (if any besides the crossmember) would I need for the transmission swap? If I just buy an AOD and do it, i know that PATC has the entire kit for $600, but I'm assuming I wouldn't need most of it if I do the engine and tranny together.
Any technical advice?
