Could anyone here please enlighten me the differences between these two Allison automatic transmissions, and to list the complete specifications for both models?

As far as torque converters go, I do know, however, that the MT647 (and the earlier MT644) does share its with the HT7xx series.

Thank you,



Benjamin "Ben" Edge

I actually had posted that one myself four years ago if you must know:

Anyways, the reason I thought I'd give it a shot here is because in that link, those I wrote by hand may not match up 100% to the official Allison spec sheets, since not a whole lot of you here know much regarding the MT644/647/648/654CR.
