Fmtv 6x6 engine and tranny

[Davidl13]

I am looking at an fmtv with a cat 3126b or c7 and they all come with the 7 speed Allison MD-D7 transmission.

1. Does anyone know if you can direct swap a cattepillar c15 in this vehicle?
2. Does the c15, if swappable, bolt up to that tranny?
3. What is the horsepower and torque rating on the md-d7 transmission?

Thanks in advance

I doubt it'll fit. It's tight and the C15 is big, heavy and powerful.

and the Allison isn't rated for that kind of power even if it would bolt up.

I can't seem to find the spec for that tranny... I see the c7 can be squeezed up to about 375 hp...

i also see allison makes a current 4000 series that will go up to 600hp...

Do you know where to find the Allison spec for the MD-D7...?
