5. Correct fluid level is
displayed as shown.
6. Low fluid level is
displayed as shown. The
number indicates the
number of quarts of fluid
the transmission
requires.
7. High fluid level condition
with the number of quarts
in excess is displayed as
shown.
NOTE
Confirm a low fluid level condition by making a
manual fluid level check.
8. To exit the Oil Level Display Mode, press
any range button «R», «N» or «D» at any

3.3 RECOMMENDED AUTOMATIC
TRANSMISSION FLUID
Only use fluids meeting Allison Transmission
specification TES295 or TES389 in your
transmission. Refer to TES295 or TES389
Approved Fluids list, found under the
Service/Fluids heading on the home page of the
Allison Transmission web site
www.allisontransmission.com.
Allison Transmission recommends you take the
following into consideration when selecting the
appropriate fluid type for your transmission:

Fluids meeting specification TES295 are
preferred over TES389 fluids for use in all
4000 Product Families transmission
applications.

TES295 fluids are fully qualified for Severe
Duty and Extended Drain intervals.

A TES295 fluid allows you to operate at a
lower ambient temperature than a TES389
type fluid.

TES389 fluid is the minimum fluid
requirement approved for use in 4000
Product Families transmissions.

To extend the TES389 fluid drain intervals
beyond the recommended mileage or hours
change interval, use a fluid analysis
program.
When choosing a fluid type to use, consider
what the minimum fluid operating temperature of
the fluid will be based on the ambient
temperatures reached in the geographical
location for the vehicle.
