Allison Transmission Filter Change Interval (New Policy)

[Always-RVing]

Well, apparently, this has been around for several years, but the docs and dealers are not telling you.

This just saved me a bunch of $$$.

I just talked to Allison and the initial 5,000 mile filter change requirement was done away with when they introduced the high capacity filter.

Follow the below link/pointer for your transmission.

The requirement now for the 3000MH is: 36 mos Filter, and 48 mos Fluid when using the High Capacity Filter (Which is the only one used since something like 2006, maybe earlier)

Fluid/Filter Change Intervals: Service: Allison Transmission

Fluid/Filter Change Intervals: Service: Allison Transmission

To be exact, get the tranny serial number and call Allision: 800-252-5283


Wow!!! 300,000 miles or 6,000 hrs for the fluid

Oh!!! One more thing, for the 3000MH, you'll lose 10 qts of fluid for the filter change and 19 qts for complete fluid change.

We've had this posted as a sticky for 2 1/2 years.

Because of this, Freightliner suggests you just change both fluid and filter every 3 years. That way, you keep changing both together, and not filter without fluid, or fluid without filter.

Batman, I recently sent an email to Allsion and recommended they consider changing the (main & lube) filters at 48-months when you use Transynd fluid and Allsion high capacity filters. This would eliminate having the expense to change the filters at 36-months and turn around in one year and then have the fluid changed. You lose about 10-12 quarts of fluid when you have just the filters changed. It would certainly save us money in the long run. If Transynd fluid is a good as they say it is then it should be a consideration.
