Check the new Mopar Action mag. There's a full tear down article of the Passon tranny in it. I was referring to the internal rail shifting of the Tremec units I don't care for. The Passon unit mimics the Mopar 833 with serious upgrades in longevity and durability. It's an aluminum case rated at 650ft;lbs. The gears are 27% wider with tapered bearings throughout the trans. It will fit an A-body with no body/frame mods. In the article they show the new trans beside an old 833 & you can see how it will fit. I'm foaming at the mouth right now!!!!!!!! I can't wait!:burnout:
