Transmission Shifter - Operation

OPERATION

DRIVE range provides FIRST, SECOND, THIRD, FOURTH, OVERDRIVE FIFTH, OVERDRIVE SIXTH gear ranges. The shift into OVERDRIVE FOURTH and FIFTH gear ranges occurs only after the transmission has completed the shift into D THIRD gear range.

The SIXTH gear upshifts occur automatically unless the Tow/Haul or OD Off mode is enabled. No upshift to FIFTH or SIXTH gears will occur if any of the following are true:

- The transmission fluid temperature is below 5° C (41° F).
- The shift to Fourth is not yet complete.
- Vehicle speed is too low for the 4-5 or 5-6 shifts to occur.
- Transfer case is in low range.

Upshifts into FOURTH or FIFTH will be delayed when the transmission fluid temperature is below 4.5° C (40° F) or above 115.5° C (240° F).
