HYDRAULIC SYSTEM – Continued
Action of Hydraulic System in High Range, Lockup Drive, Left Steer
NOTE
Refer to Torque Path in High Range, Lockup Drive Left Steer Schematic View for torque path
through the transmission and the Action of Hydraulic System in High Range, Lockup Drive,
Left Steer Schematic View. The description of hydraulic system in high range, lockup drive,
no steer applies to this paragraph. The only differences are that the steer pressure is not
blocked at the steer valve and lubrication pressure is not blocked at the left steer clutch.
The description in the action of the hydraulic system in neutral, converter drive, right steer applies to this paragraph.
The only differences are that reference to “left” and “right” must be reversed, as well as references to “upper” and
“lower.”
