Transmission

Transmissions are fully automatic 4 or 5-speed consisting of a 3-element welded torque converter, 2 or 3 compound planetary gear sets, 2 or 3 multiple-disc clutches, one overrunning clutch and 3 brake bands. Brake bands control function of planetary gear sets. A hydraulic system, pressurized by a primary gear type pump and a secondary piston type pump provide working pressure required to operate friction elements and automatic controls.

Precautions for Battery Service
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.

This transaxle uses two lubrication mechanisms concurrently: a lubrication mechanism consisting of a trochoid type oil pump placed on the main shaft, and a lubrication mechanism consisting of an oil slinger on the final gear. The concurrent use of the two mechanisms reduces the drive loss of the oil pump.

This Self-Study Program provides you with the design and function of the new 6-speed automatic transmission, which is installed in the Touareg.

The 0C8 8-speed automatic transmission is based on the previous 09D automatic transmission. This transmission uses the same basic components and has added two more forward speeds, helping both performance and fuel consumption.
All 2011 Touareg vehicles will have the 0C8 8-speed automatic transmission
