1992 Dodge Dakota 518 overdrive transmission

Question>>>Cant you just run a toggle switch on the computer controlled one to switch on the OD or is it more complicated than that. If it is an A500 with the capability to just use a switch to engage the OD I would be interested. If it is an A500 does anyone know if it will fit in a 70 Dart Without major surgery. I wouldnt mind a few blows to the tunnel with a sledgehammer but am not equipped to do major surgery. With an A500 is there major crossmember frigging??


Major frigging of crossmember is needed, ie. you have to cut yours in half and graft in a center section to support this guy. also you need to literally cut your tunnel out and weld in a larger tunnel as the O/D tailshaft is about 10 inches wide as opposed to your 4 inch 727/904. Lots of work. But having an overdrive with street gears is...priceless.
