malfunction. However, neither the engine nor

transmission are negatively affected by this mode of

operation.

The delayed upshift is effective with vehicle speeds

below 31 mph (50 km/h) at partial throttle and engine

temperatures below 95

°F (35°C).

To avoid overrevving the engine when the selector lever

is moved to a lower gear range, the transmission will not

shift to a lower gear, if the engine’s revolutions per

minute limit would be exceeded. In this case there will

be no downshift, even when the vehicle speed reaches

the engine’s rpm limit of that gear, e.g. by applying the

service brakes.

To prevent the engine from laboring at low RPM when

driving uphill gradients or with your vehicle heavily

loaded, the automatic transmission will downshift when

necessary to maintain engine RPM within the best

torque range.

Gear ranges:

Upshift through 4th gear only. Suitable for

performance driving.

Upshift through 3rd gear only. Suitable for

moderately steep hills. Since the transmission

does not shift higher than 3rd gear, this gear

selection will allow use of the engine’s braking

power downhill.

Upshift through 2nd gear only. For driving in

mountainous regions or under extreme operating

conditions. This gear selection will allow use of

the engine’s braking power when descending

steep grades.

Use this position, which makes maximum use of

the engine’s braking effect, while descending

very steep or lengthy downgrades and only at

speeds below 40 mph (60 km/h).

Note:

To avoid overevving the engine on rpm limit, the

transmission will upshift automatically to the next

higher gear as long as the vehicle is accelerating.
