The Stovebolt Site Forums The Parking Lot Big Bolts 1955 GMC 550

I just got a book from '60 that shows a Torquematic, really an Allison auto. It was on bigger trucks and engines. What engine do you have? Could be some oddball. Pontiac 322 is listed in this book or Motors manuals. Not sure on olds ID. I'ld say, if the trans and box work now, leave it alone. I bet the orig trans set-up would be "Unobtainium" material. Even the old 60's GMC's had adapters and such needed to use that trans on their V-6's. But yours would have to be for that pontiac engine then? Don't see it being easy at all. The manual is probly far less trouble too, that's why they changed it. Those old autos weren't as trusty as new ones today.
