M939A2 tranny fluid

[pigpen60]

Is 15/40 the recommended fluid for the allison in the M939A2 dump truck? Its in Missouri and our weather is all over the place.

Is it oil ? Or is it dextron already?

Put in what is in it color/smell wise

I dont know whats in it currently, I was told it wasnt showing on the D/S and that I needed to figure out what to use. So if its ATF I use Dextron? and if its Motor oil I use 15/40?.

Change the spin on filter under the hood. Probably needs it anyway and you will know which. Cheap NAPA 1268 or wix 51268 and a qt of whaever fluid you have. Can not remember if it has a fluid sample port also?

 

[pigpen60]

Ok, will do. Where is the filter at in the engine bay?

Not sure what fluid you are going with but another member found a good deal on full synthetic ATF buckets with me off ebay and also Napa sells buckets of dex 3 for about $65.00

Has anyone used tractor transmission/hydraulic fluid such as Case Hy-Tran? My tractor loves it, just wondering what it would do in an Allison.

Don't know which transmission it is.
