I have a 2001 Freightshaker with a Cat c-12 and an Eaton 10 speed. When shifting from low to high range I get a sharp, quick grinding noise. It doesn't catch or anything, in fact I can barely feel it through the shifter, it just sounds terrible for about 1 second. It used to do this occasionally and I thought it was just the nature of the beast but now it does it every single time. Only when shifting from low to high range in any gear. It has 615,000 mi. But it was gone through about 30,000 mi. ago.
Is it something I should have checked out before it causes more damage? olwhda

There is an air shifted slave cyl under the top trans cover ,its a dirty job ,and a bit hard to stab it back .

But the average farmer could change the "o" rings on it .

I guess I'm not sure if it is a super 10. You shift through 5 then lift the lever to high range and shift 1-5 again. Lunatic Fringe

I kind of think it may have something to do with the air cyl. not shifting from low to high quick enough or dragging. What do you mean by " stabbing it back" ? olwhda

Regular 10 speed, Super 10 shifts like a 5spd with 2spd axle. play in the dirt

I may not have the correct terminology but it sounds like the synchronizer is bad for the range selection. Happen to mine and I just had the transmission rebuilt but I had quite a few more miles on mine than you do yours. I'm sure someone like Tommy can explain things better and tell you what you need to do. I don't quite understand what he was trying to say in his previous reply. sdan27

We had the same issue with a 13-speed in a dump truck. As was previously stated, it is the synchronizer that helps it shift between high and low range that is getting worn out. Ours got so bad that it finally wouldn't stay in high range and would basically slip back into neutral I think. You'll have to remove the rear section of the transmission in order to service it properly. Unless you have much experience or know how on those, I'd recommend taking it into a truck shop, that was what we did. milofarmer1

You need to do this or have it done. Because if that is the problem it will take out the synchronizer letting it grind like that over and over. It could also be the air line to the shifter plugged and not letting it shift quick enough. May be too late either way.

There is a little air powered cylinder that shifts the transmission from high to low - (think planter markers high is down ,low is up )

This little cylinder will leak and not make a full shift ,and grind the syncros .

The top cover on the transmission has to come off ,what is hard is putting the top back on ,getting all the shift forks stabbed .

It is a tough job ob the first one you do ,but ill bet a truck shop would charge at least 1000 to do the job .
