The donor chassis for my 56 Dodge pickup is my 2001 Dakota with the 5-speed manual. When I change it over to a 545RFE automatic, what will I have to change chassis wise? Harness? Connections at the instrument panel? Controller? Connections to other systems? I plan to keep the floor shift console, use a Lokar or American Shifter to control the trans. I already have a different instrument cluster with the shift indicator.
