Introduction
The 5-Speed Automatic
Transmission 09A/09B
• Tiptronic
• Shift indicator in instrument cluster
• Ignition key removal lock
• Torque converter with torque converter
lock-up clutch
• Stationary decoupling:
When the vehicle stops and a forward
drive position is engaged, the
transmission changes into neutral.
Advantage:
The vehicle shows no tendency to creep,
which means higher fuel economy and
lower emissions.
The new 5-speed automatic transmission
is built by Jatco, the well-known
automatic transmission manufacturer.
The transmission was adapted to the
vehicle and the TCM software in
cooperation with Volkswagen’s engineers.
This transmission is notable for the
following components and functions:
• Automatic shifting of the five gears by
driver and situation dependent driving
programs
• A drag-dependent driving program
(recognizes traction resistances when
driving uphill and downhill, when
towing a trailer and when driving into
a headwind)

The ATF oil is designed to last for the service life of the transmission. It also lubricates the final drive.
