In Park range, there are three levels of power flow coexisting. The graphics will follow each flow separately by numerical designation, in relation to the following text.

Torque from the engine is transferred to the transmission through the engine flywheel which is bolted to the torque converter assembly (14).

As the torque converter turbine rotates, the 5-7-reverse and 6-7-8-9 clutch housing (530) and the turbine shaft (547) which is splined to the torque converter turbine, is also forced to rotate at turbine speed.

The input sun gear (551), which is splined to the turbine shaft (547), drives the input carrier assembly (552) pinion gears.

The input carrier assembly drives the output carrier assembly (555) pinions.

The output carrier assembly (555) is splined to, and held by, the output carrier transfer drive gear hub (502). The output internal gear (input carrier assembly) (552) drives the output carrier assembly (555) pinions, which then drives the output sun gear (522).

Without the 1-2-3-4-5-6 clutch applied, torque cannot be transferred from the output sun gear (522), thus power flow is terminated.

Torque from the vehicle travels through the wheels to the front differential carrier (238), and is transferred to the front differential carrier sun gear (240), which is splined to driven sprocket (241).

The park lock gear is held by the park pawl (715). The park lock gear is splined to the output carrier transfer drive gear hub (502). Therefore power flow is terminated at the output carrier transfer drive gear hub (502).

The drive sprocket (234) is in mesh with the drive link (233), which is in mesh with and held by the driven sprocket (241).
