Operating Instructions Operating the Transmission
Model 330 PB1318 3/01
– 69 –
Vehicles equipped with the MD transmissions have various
diagnostic features. They include a “DON'T SHIFT” light, plus
diagnostic codes that appear in the digital display on the shift
control unit, audible alarms that sound, and connections for
hooking up a data reader (for service only).
The “DON'T SHIFT” light (located on the dash) will come ON
when the engine is first started, then go OFF after a few sec-
onds. The transmission is automatically controlled by its
Electronic Control Unit (ECU); therefore, if the “DON'T
SHIFT” light comes ON during operation, the ECU has
placed automatic controls on the transmission—canceling or
ignoring your selections. Please see the transmission

tor’s Manual
