M1028 Cracked Transmission Case

[MachoTime96]

Just found a crack in the rear of the Transmission case on my 1984 M1028. Thinking of replacing the entire thing.

Any videos, links, advise is appreciated, thank you in advance.

Yessir, I believe you will need a replacement case.
Did you "dog" your truck, or was it already broken when you got it?

Not sure was "dog" means but i dont believe it was broken when I got it. I drive it carefully on mostly pavement.

Okay, what about the motor / transmission mounts? Are they in good shape? Generally speaking, a transmission will only get cracked if it is under a load (torque) and maybe the mounting was loose. I can't imagine it just sitting there and getting a crack in it.

Fork lift loading to sell at auction has done that many time in the past.

You may be on to something. I noticed my rear drive shaft was dented. The previous put a tire weight to offset the dent when it spins. This could be a factor. Ive yet to check the motor mounts. But ive never noticed them being worn.
