Refer to Torque Path In Neutral, Converter Drive, No Steer and The Action Of Hydraulic
System In Neutral Converter Drive No Steer.
In neutral, the engine delivers torque to the transmission through the torque converter. Lockup cannot occur.
No clutch is engaged but the torque converter turbine shaft is driven by the action of the torque converter when en-
gine speed is sufficient. However, when engine speed is low, torque action is not sufficient to rotate the turbine or the
Pivot steer is the ability of a vehicle to turn about its center without traveling in either a
forward or reverse direction. This results when the vehicle tracks move in the opposite
directions at equal speeds.
In addition to its connection with the drive ranges, through the range clutches, the turbine shaft connects to
the steer system and rotates the right and left steer clutch drive gears. This makes pivot steer available in neutral.
If steer is not applied, the steer clutches are released and the steer clutch drive gears rotate freely when the
vehicle is accelerated.
