Hello,
This is my first post after a unsuccessful search of the forum. I have a 06 kodiak super c with an 8.1 engine and an Allison transmission. My problem is a clunk noise when the tranny downshifts at highway speeds going up hill. I've changed the tranny fluid and filter but with only 40000 miles I can't see it needing transmission work. Any thoughts would be appreciated.
Thanks
Paul

Did you check the U joints on the drive line?

When you check the ujoints, check any carrier bearings and any slack in the differential input.
