Driving
+ and - position operation
These positions allow the driver to
manually select the appropriate
upshift (+) or downshift (-) and
gear range.
Can only be entered from the D5
(Overdrive) shift position.
Gear ranges 1–5 provide the same
function and ratio as found in the
D5 or D4 automatic mode positions.
The transmission will not upshift or
downshift unless the gearshift lever
is moved forward or rearward.
One tap forward (+) will
command the transmission to upshift one gear range.
One tap rearward (-) will command the transmission to downshift one
gear range.
Upshifts are allowed at any vehicle speed.
2 (Second) gear is normally used for start-up. A 3 (Third) gear
start-up will be allowed only if selected. All other selection(s) will
revert to 2 (Second) gear.
If the driver starts in 2 (Second) gear and does not pass a throttle
angle of 60%, the transmission will remain in 2 (Second) gear. No
automatic upshift will occur.
If the driver passes the 60% throttle angle, a 2–1 kickdown will occur,
scheduled by the processor as used in D5. Once the 2–1 kickdown has
occurred, the transmission will remain in 1 (First) gear until 2
(Second) gear is manually selected by moving the gearshift lever. No
automatic upshift will occur.
Once a 2–1 kickdown has occurred, manually shifting in and out of 1
(First ) gear is allowed until the vehicle comes to a complete stop.
A shift to 1 (First) with the vehicle at a stop is never allowed.
When downshifting at normal road speeds, the transmission will only
allow a downshift into the next lower gear.
If the gearshift lever is moved into the downshift (-) position more
than once in rapid succession, the transmission will only allow a
downshift into the next lower gear to prevent possible engine and/or
transmission damage. Once the vehicle reaches below a specified entry
