Allison trans currently has Rotella 15w40 for ATF.
Any thoughts on this or changing to another ATF would be appreciated.
Merry Xmas.

I'm a semi mechanic at UPS. The spotter trucks that all have an Allison automatic called for a 15W40 engine oil
up until about 12 years ago. Those transmissions hold up fine on it pulling semi trailers around the lot.

I don't know about the newer transmissions, but a lot of the older allisons could run hydraulic fluid , dex III ATF or 10w-30/15w-40 engine oil

Current fill will likely last the entire time you own the truck.

Does it use a spin on filter?

Thanks for the replies.
I'll look for the spin on filter.
The internal filter is identical to a TH400.
Thoughts on T6 in the engine?
Merry Christmas to all.

It does have the spin on filter.
It's very slow to shift when cold.
Then, again, everything is slow on this truck. Really like it. Rough ride, tough to steer, and brakes work great but you really have to stand on them.
It's a stinking blast to drive.
52-54 MPH tops.

For logistics purposes the US Army wanted to have a common engine and trans oil. The 15W40 was the diesel engine oil specified under MIL-L-2104D. So the trans was validated on both Dexron and engine oil. If you want better low temp performance, you could use a Dexron III spec oil or a 0W20 engine oil. 0W20 synthetic engine oil was the Army spec for engine and trans in arctic climate usage.
