HYDRAULIC SYSTEM – Continued
Action Of Hydraulic System In High Range, Lockup Drive, Left Steer
NOTE
Refer to Torque path in High Range, Left Steer schematic view for the torque path through
the transmission.
When in high range, lockup drive, left steer, the system is the same as described for intermediate--range op-
eration, above. The only difference is that the range selector valve directs pressure to the high--range clutch instead
of the intermediate--range clutch. The converter lockup valve is controlled by throttle position. Refer to description in
intermediate--range operation.
In high range, the shift inhibitor will prevent a downshift to intermediate range (or low and reverse range) until
vehicle speed is reduced to a safe level.
