Recommended Vehicle Shift Speeds
To utilize your manual transmission efficiently for both fuel economy and performance, it should be upshifted as listed in
recomme
nded shift speed chart. Shift at the vehicle speeds listed for acceleration. When heavily loaded or pulling a trailer
these recommended up-shift speeds may not apply.
NOTE:
Vehicle speeds shown in the chart above are for 2H and 4H
only, ve
hicle speeds in 4L would be significantly less.
Downshifting
Moving from a high gear down to a lower gear is recom-
mended to preserve brakes when driving down steep hills.
In addi
tion, downshifting at the right time provides better
acceleration when you desire to resume speed. Downshift
progressively. Do not skip gears to avoid overspeeding the
engine and clutch.
NOTE:
Above certain speeds downshifts may be blocked and not
availab
le.

WARNING!
Do not downshift for additional engine braking on a
slipper
y surface. The drive wheels could lose their grip,
and the vehicle could skid.
CAUTION!
Skipping gears and downshifting into lower gears at
higher
vehicle speeds can damage the engine and
clutch systems, Any attempt to shift into lower gear
with clutch pedal depressed may result damage to the
clutch system. Shifting into lower gear and releasing
the clutch may result in engine damage.
