Manual Second Gear (L4 Hybrid): Notes

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

A manual 3-2 downshift is initiated by moving the gear selector lever to the Manual Second (2) position. However, the transmission will not downshift into Second gear until vehicle speed is below approximately 99 km/h (62 mph). At higher vehicle speeds the PCM will keep the 2-3 shift solenoid energized (On) and the transmission will operate in Manual Second - Third Gear as a safety precaution. In Manual Second the transmission is hydraulically prevented from upshifting into Fourth gear under any conditions. Also, the coast clutch remains applied as in Manual Third, and the clutch provides engine compression braking in the Third and the Second gears. The transmission upshifts and downshifts between First and Second gears as in Overdrive gear.

Under certain conditions the hybrid vehicles engine will shut off and the electric auxiliary transmission fluid pump will start running to keep the transmission pressurized and ready for the engine restart. This engine off condition is a fuel economy feature and the L4 hybrid transmission's electric auxiliary fluid pump is an enabling component.
