Just plunked down a huge chunk of change for a brand new, factory built Allison tranny (gulp!). After a year of passing on what few 6-speeds I could find I bit the bullet. It's a 2200MH, double overdrive, 6-speed auto with a parking pawl. As it turns out, probably only about a grand more than what I figured rebuilding some unknown used unit to my specs would likely run. Still a lot to pull together to make it work, but at least that's one more major item to cross off the "must-do" list.
Anybody happen to have a transmission wiring harness from an International truck with a 1000/2000 series Gen 4 Allison laying around?
