THROTTLE CONTROL
The position of the throttle influences the automatic shifting. At wide open throttle, the
transmission will upshift automatically near the governed speed of the engine. At part
throttle, shifts will occur at a lower engine speed. When modulated lockup is
provided, closed-throttle operation delays the release of the lockup clutch to provide
additional engine braking at lower vehicle speeds.
DOWNSHIFT INHIBIT FEATURE
The transmission hydraulic system will inhibit a shift into any range at a speed that
will cause engine overspeed. Any lower, forward range may be selected at any time,
but the actual engagement will not occur until road speed is reduced; downshifting is
progressive as road speed decreases. The inhibit effect will cause downshifts to occur
at slightly higher speeds than normal automatic downshifts.
OPERATING IN COLD WEATHER
Refer to Table 2 on Page 31 for the minimum fluid temperatures at which the
transmission may be safely operated in a forward or reverse range. When ambient
temperature is below the minimum fluid temperature limit and the transmission is
cold, preheat is required. If auxiliary heating equipment is not available, run the
equipment or vehicle with the transmission in neutral for a minimum of 20 minutes
before attempting range operation.
CAUTION: Never shift from N (Neutral) to D (Drive) or
N (Neutral) to R (Reverse) at engine speeds above idle. The vehicle
will lurch forward or rearward and the transmission can be damaged.
CAUTION: Disregarding minimum fluid temperature limits can
result in transmission malfunction or reduced transmission life.
