Hey all,
I am Typ4's son Brandon.
I have a quick question regarding Detriot engines.
My 1955 GMC coach has a 6-71 in it matched up to an Allison VH transmission (single speed, converter lockup or unlocked).
I am interested in swapping in a newer transmission but they all come off of 6v71 engines (Like the Allison V731 series 3-speed auto).
Anyone have an experience with these? Is the swap possible? There are also VH-3 and VH-5 transmissions out there, but even those are starting to become 35+ years old and thus a little hard to get hands on.
Any help would be appreciated.
If I had my hands on a different powerplant that would fit, I would swap it all over to CAT or Cummins power for some real getup-and-go. For now the Detroit does a good job of turning diesel into noise.
I will do a posting soon of the project
P.S. I am also looking for a 6-71 head w/ Jacob Brake (Jake Brake)
Later,
