Ultashift Tune Up?

jjoerger · May 27, 2011

Is there such a thing as a tune up for an Eaton Ultrashift transmission? Like a fluid change, clutch adjustment, etc. Whatever should be done on a regular service basis.
Nothing has been touched on ours since the clutch replacement about 150,000 miles ago.

Treat the transmission for what it is a manual transmission. Check the oil level regularly and Bob is thinking the book says 500,000 miles to have the oil changed. Check in your owners manual for the specifics on the mileage.

I would have Eaton to look at getting the ECM reprogrammed for progressive shifting.

As per what Greg said. I have had two of these and you can get the shift points set for your present needs. I seem to run back from the west coast grossed out so I have the shift point set to up shift at 1750 rpm and down shift at 1350 rpm. Helps out going over the Rockies. I don't think I would go back to a manual clutch getting old and layz

How would that help me? It seems to shift fine as it is and we are getting right at 10 mpg on the long runs.
Who would I take it to for that type of work. Would they know if it would benefit me and what it should be set at for my specific application? I am totally unknowledgeable on this subject.

The tune up actually conists of hooking the computer up to the ECM plug in the cab and programming the unit for economy ie: progressive shifting or a more aggressive shift schedule. Any dealer should be able to do this. If it is working fine and miles are good on service points, you may want them to see if the Clutch Brake needs adjusting if you do anything at all. I had over 800K on last unit with no problems.
