Engineered specifically for the Allison TES-295 transmission fluid specification. Replaces Allison/Castrol Transynd® fluid. Excellent protection in temperature extremes. Ensures consistent, smooth clutch engagement over the life of the fluid and controls clutch glazing and elongated shift times.
Check your owner's manual. Gotta have the info there. If it is ATF then Transynd is an excellent choice and you can run it in your transfer case as well. Of course the Amsoil mentioned would work well too, it is their version of a TES 295-type syn transmission fluid.
