posting this for a friend, he got his 99 3500 6spd dually stuck on a hillside in the mud, when i got there to help out tires were spun down into the mud and it was generally buried. issue is, no gears, 1 through 6 and reverse, nothing, not even any load, clutch was replaced 6 mos ago and truck has sat for most of that, a few drops of red oil coming from trans body but i don't know if that was there 1st or not. any help appriciated.

 

Input shaft?

Any noises when you let out on the clutch? Does the clutch feel normal?

 

transfer case is ok?..... not in neutral or linkage problem.

 

That's what I was thinking.

 

DOH, never thought about it, simplest thing first....................

 

all gears in all transfer case positions, no noise from case or trans itself, not even any slightest motion at driveshaft.

 

I'd put my money on a broken input shaft.
