OPERATION
Drive range provides underdrive FIRST, SECOND and THIRD gears, direct FOURTH gear and overdrive FIFTH and SIXTH gears. The shift into
overdrive FIFTH and SIXTH gear occurs only after the transmission has completed the shift into FOURTH gear. No other movement of the shift
mechanism is required to complete the 4-5 or 5-6 gear shifts.
The FOURTH and FIFTH gear upshift occurs automatically unless the Tow/Haul mode is enabled.
Upshifts into both overdrive gears, FIFTH and SIXTH, will be delayed when the transmission fluid temperature is below 4.5° C (40° F) or above 115.5°
C (240° F).
