transmission system, the lights will go out. Whenever
there is a problem with the transmission system, the
lights will come on and stay on as long as the problem
exists.
If "service" is displayed in the indicator panel, some fea-
tures may not work, but the vehicle can still be driven. If
the do-not-shift light comes on while driving (accompa-
nied by eight short beeps from the shift selector), oper-
ating limits will be placed on the transmission, such as
restricting upshifts and downshifts. However, the vehicle
can still be driven to reach service assistance. In either
situation, have the problem repaired as soon as pos-
sible. Refer to the
Allison Transmission Service Manual
for troubleshooting procedures.
See Chapter 5 for complete transmission operating
instructions.
