STEP 2 — Answer these questions about your vehicle.

Is the transmission equipped with an output retarder, or is it used in an application with a duty cycle greater than one (1) stop per mile, or does it operate On/Off Highway?

Yes
No

What type of fluid does the transmission currently contain? *

	100% Allison Approved TES 295 fluid (no mixture)
	100% Allison Approved TES 389 fluid or mixture of Allison Approved TES 389/TES 295 fluid
	Other

* Mixture is defined as the quantity of Allison Approved TES 389 and Allison Approved TES 295 fluid remaining in the transmission after a standard fluid change.

If the transmission contains such a mixture, it is not eligible for the 100% concentration extended change intervals, until the second consecutive fluid change using Allison Approved TES 295 fluid.

Fluid exchange (purge) machines are not recommended or recognized due to variation and inconsistencies with ensuring removal of 100% of the used fluid.
