TRANSMISSION SHIFTING INSTRUCTIONS

CAUTION
The maximum safe operating oil temperature for MACK transmissions is
121°C (250°F) for mineral-based oil, and 148°C (300°F) for synthetic-based
oil. Continued operation with oil above this temperature will result in rapid
deterioration of the oil's lubricating properties and is NOT recommended.
CAUTION
To avoid transmission damage, the vehicle must be completely stopped before being
shifted from REVERSE to any forward speed (and vice versa).
CAUTION
Never coast with the transmission in neutral. Never coast with the clutch depressed.
