Allison MT643?
 

Anybody have this tranny? Anyone know the pros/cons of this tranny? What would need to be done to do a swap to this tranny into a 98 dodge 3500 12v auto?

I'm looking at buying this trans for $900 out of a 96 school bus. The tranny comes with the flywheel, flex plate, torque converter, bolts, AND engine flywheel housing removed from a 12V 5.9 Cummins.

Thoughts? :humm:
All input is very welcome! need to make a decision on this quickly!

pros: pretty much bulletproof trans and will take alot of abuse

cons: monster 500 lb trans --swap is a little complicated--

thats a good price for all your getting, compared to a 47re its a pretty big upgrade and might just be the last trans work you ever do after the swap is done

would be cool to hear more about the swap if it happens,
good luck
