If you must add transmission fluid, see your Allison Automatic
Transmission Operator's Manual for the correct fluid type. Use of a
non-approved automatic transmission fluid may cause internal
transmission component damage.
Fluid levels above the safe range may result in transmission failure. An
overfill condition of transmission fluid may cause shift or engagement
concerns or possible damage.

See the Scheduled Maintenance chapter for scheduled intervals for
fluid checks and changes. Your transmission does not consume fluid.

working properly. For example, if the transmission slips or shifts slowly
or if you notice some sign of fluid leakage.

accurate fluid check, drive your vehicle until it is at normal operating
temperature, approximately 20 miles (30 kilometers). Verify that the
transmission fluid temperature gauge, located on the instrument cluster,
is within the normal range.
