DRIVE 3 — Four-Speed Transmission
This range eliminates shifts into fourth gear. The trans-
mission will operate normally in first and second gear.
Shifts into third gear may be delayed to provide second
gear operation at higher speeds. The ⬙3⬙ range should
also be used when descending steep grades to prevent
brake system distress
NOTE: Using the ⬙3⬙ range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build-up.
LOW — Four-Speed Transmission
This range should be used for engine braking when
descending very steep grades. In this range, upshifts will
occur only to prevent engine overspeed while downshifts
occur earlier than other gear range selections.
CAUTION!
If the transmission operating temperature exceeds
acceptable limits, the vehicle computer may override
the manually selected gear position by changing shift
points. This is done to prevent transmission damage
due to overheating.
Reset Mode - Electronic Transmission
The transmission is monitored electronically for abnor-
mal conditions. If a condition is detected that could cause
damage, the transmission automatically shifts into sec-
ond gear (third gear for six–speed). The transmission
remains in second gear (third gear for six–speed) despite
the forward gear selected. PARK, REVERSE, and NEU-
TRAL will continue to operate. The Reset feature allows
the vehicle to be driven to a dealer for service without
damaging the transmission.
