When to use 2 (Second)
Use 2 (Second) to start-up on slippery roads or
to provide additional engine braking on
downgrades. This position provides 2 (Second)
gear operation only.
When to use 1 (Low)
Use 1 (Low) to provide maximum engine
braking on steep downgrades. Upshifts from 1
(Low) can be made by manually shifting to 2
(Second) or j (Overdrive). Selection of 1 (Low)
gear provides only low gear operation from
start-up. Selection of 1 (Low) while at higher
speeds provides a shift to second gear, and a
shift to first gear will occur after the vehicle
decelerates to the proper speed.
Forced Downshifts
To gain acceleration in j (Overdrive) or Drive
(j position with Overdrive cancelled) when
passing another vehicle, push the accelerator to
the floor. The transmission will downshift to the
appropriate gear: third, second or first.
Driving (5R55E Transmission)
When to use j (Overdrive)
This is the normal driving position. As the
vehicle picks up speed, automatic upshifts to
second, third, fourth and fifth gears will occur
when j (Overdrive) is chosen on the selector
and the transmission control switch has not been
pressed. The transmission will shift into the
correct gear when the right speed is achieved,
for the accelerator pedal position you have
chosen.
