Toasted 4x4 FM145?

[ronclark]

I was out and about today, when I left the parking lot my truck moved 10 feet and stopped it would not move in any of the gears, I finely did get it move and heard a pop sounds inside the trans.
it drive home just find and it had oil in it.
I am guess it might be toast so it it worth rebuilding or find a stronger replacement

The M5OD is a lot stronger, but since you have an FM145 you're going to need different driveshafts.
