Technical Support / Re: Allison Transmission Hard Shifting

Wow,

“when it will fail not if it will fail.”  That’s just about every major component on the coach. Traveling several thousand miles with zero issues with transmission, I think I would hold off on replacing transmission. There are no guarantees that a rebuilt or remanufactured trans will be any better. Just my humble opinion for whatever that’s worth. Good luck on your decision.

Update:

I took the coach on a trip from Chicago to the Florida Keys for about the last month. The transmission did well. I saw temperatures ranging from 155 to 185 from flat Indiana in the cold to the hills in southern Georgia. Although I got over 2000 miles out of the transmission, it was always in the back of my mind that it's when it will fail not if it will fail. I decided upon my return this past weekend that I will be ordering a reman transmission. I got a few quotes from $10,250.00 at the high end and the lowest at $7,900.00. I will be going with the lowest as they are a major local Allison distributor I have worked with and have a 2 year unlimited mile warranty. Just wanted to let everyone know how it went.

Thanks for the replies  Coach has been at Cummings in Tampa since Jan 19th.  That is the part number that is on my estimate.
Coach was taken in for another problem with Gen  It would cut off after 25/30 mins like it was hot but engine was not hot,  Had the belt, thermostat, and heat sender changed did not solv problem  Took it to Cummings they diagnosed it as needing new PCB
(1400.00) in that process they said brushes were within tolerances but barley.  So i made decision to change Brush Bloch While
it was there.  Was told there was none available in the Cummings system they would have to order thru their national parts dept.
Just thought someone might have had same problem  I have told them to put old brushes back and install new PCB just hope this solves the original problem.(2600.00) OUCH
Thanks for the FORUM.

Are you sure you have the right part number or was it superseded by another number? I would check back with a onam dealer.

Since Cummins owns Onan, would a Cummins service center be able to help you?

Good luck!

On our 06PT I changed one of our valves to a manual but kept the other as electric. The manual valve is availble from many suppliers try Amazon server drain gate valve they will cost 20-30 dollars and very EZ to change youself . When I sold our 06PT I did pull the manual unit and installed the electric very EZ and maybe [$30.00)

Robert,

Try opening the valves with engine running or when plugged in. The higher voltage helps get the valve motor moving easier. Hope this helps.
