Allison Transmission Service Interval

We made it back from our amazing 3 month trip out west to humid Florida only to find our house Air Conditioner DOA New system is being installed as I type.

I just called my local Freightliner dealer to set up service next week. I have 15,000 miles on the Seneca (2nd oil change) and was advised to change the transmission fluid. I believe Allison suggests changing at 24,000 miles for severe service, which I am sort of willing to consider ours to be.

What are your thoughts on changing the transmission fluid this early? I am thinking it couldn’t hurt, assuming the tech does it correctly. The suggestion took me by surprise.

When do others with Seneca’s change transmission fluid?

I know with the Allison 1000 the first fluid change came much sooner than subsequent ones. Also you have a truck with a house on it and a truck is a truck and the changes would be based on the model trany you have on that list.

Is taking me by surprise too... We are in the 24k range now and making me wonder too.

Don't forget about the spin-on Control Main filter, it gets an initial change at 10,000 miles or 400 engine hours, whichever comes first. It has a magnet where is screws onto the transmission that is inspected for debris, cleaned, and transferred to the new filter.

Link to Control Main filter: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Allison classifies "Severe Vocation" as stopping more often than once per mile.

Well, this has taken me by surprise also. I'll have to check this further. I can't imagine our use of going down the highway as being hard service. We have right at 60K on our 2015 unit and certainly have had no problems with the tranny or drive train. I did have small leak in the rear end that was covered under warranty and had it to a Freightliner dealer for that repair at around 20K. They did not mention anything of a fluid change in the Allison Transmission. Interesting.

I changed my filter around 10K, it does dump several quarts of fluid in the process. I carefully refilled it with the recommended Transynd fluid (Castrol brand) which took several attemps to get it "just right" when hot. My filter magnet was very clean as was the released fluid, so I felt confident my unit is "okay" right now. Was it overkill? Maybe!

I also had a leaky rear axle, but I was out of warranty. My Freightliner dealer (Young's Truck, Canton, OH) tried to lobby Freightliner to warranty it, but were unsuccessful. They took pity on me I guess, the repair cost me $500 when I was envisioning at least twice that!

Our motorhomes are not considered to fall into the "Severe Duty" categories for the drivetrain, with regular maintenance our coaches will likely fall apart before we wear out engines or transmissions!
