When I build my 56 Dodge pickup project onto my 2001 Dakota chassis, I'll change out the NV3500 5-speed manual trans for a 545RFE automatic trans. Anyone else change out their Dakota from a manual to an automatic trans? Aside from the trans and driveshaft, what else do I need to plan for? Harness? Controller? Connections to other systems? I already have another gauge set for the cab which has the transmission indicator in it. I also plan to use a Lokar or American Shifter shift control for the automatic so I'll maintain the floor shifter, floor console, steering column from my Dakota as is.
