NOTE
Refer to Torque path in High Range, Lockup Drive Left Steer through the transmission and
the Action of Hydraulic System in High Range, Lockup Drive, Left Steer. 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.
