TORQUE PATHS THROUGH TRANSMISSION
The major components of the transmission through which power flows are shown in this work package. The
following schematic views identify only those components engaged for the conditions stated. Arrows on components
indicate the torque path from input to output. Larger arrows near the schematic views indicate the direction of travel in
a straight path or steering to the right or left.
In all gear or steer conditions, input torque is transmitted from the vehicle engine to the range gearing by hy-
draulic or mechanical means. When the power flow line leads to the torque converter pump and then through the tur-
bine, the drive is hydraulic (through the torque converter) and the lockup clutch is released. When the power flow line
passes through the lockup clutch, the drive is mechanical (lockup clutch engaged).
