6-Speed Automatic Transmission09G/09M
The Japanese automatic transmissionmanufacturer AISIN Co., LTD is thedeveloper and manufacturer of the 09Gtransmission. Volkswagen engineersdeveloped the transmission in conjunctionwith Aisin and adapted it to Volkswagenvehicles.
The 09G/09M 6-speed automatictransmission is installed in the followingVolkswagen vehicles:
The size of the torque converter
The torque converter characteristiccurve of the torque boost (conversionfactor or conversion boost)
The selector lever
The ignition key removal lock

Maximum Torque Transfer Vehicles
The transmission is adapted for use withdifferent engines and vehicles by varying:
The number of disc pairs for clutchesand brakes
The adaptation of the ATF pressure onthe clutches and brakes
The configuration of gear pairs,planetary gear sets (e. g. four instead ofthree planetary gears), shafts andbearings
The reinforcement of housingcomponents
The ratio of the final drive and theintermediate drive
The transmission sets new standards fordynamics and efficiency in the diagonallyinstalled, conventional stepped automatictransmission segment through:
Low weight
High overall transmission ratio spread
Compact dimensions of thetransmission
High speed of shifting
High level of shifting comfort
The same manufacturer makes the 6-speedautomatic transmission in the VolkswagenTouareg designated 09D. Both automatictransmissions from AISIN use a Lepelletierarrangement.
The advantage of this Lepelletierarrangement is its simple, space-saving andlightweight design. It combines a simpleplanetary gear set with a subsequentRavigneaux arrangement. This makes sixspeeds possible with only five shiftingelements.

Technical Data
Depending on engine type, overall ratio is configured as 5+E transmission or as 6-speedtransmission.
For the 5+E transmission, the highest speed is reached in 5th gear. The 6th gear reducesengine speed, improves driving comfort and reduces fuel consumption:
For the 6-speed transmission configuration, the highest speed is reached in 6th gear. The 6thgear lowers transmission gear ratio and increases driving dynamics.

The appearance of the selector lever may differ for different vehicles. The operation and thefunction is the same, however, for all vehicles with this automatic transmission.
Steering wheel paddles are available as options and can also differ in appearance forindividual vehicles.
Selector Lever Positions andOperation
P - ParkBefore the selector lever can be moved outof this position, the ignition must beswitched on and the foot brake must bepressed.Additionally, the locking button on theselector lever must be pressed.
R - ReverseTo shift into this gear, the locking buttonmust be pressed.
N - NeutralThe transmission is in idle in this position.If the selector lever is in this position for along time and the vehicle is driven at lessthan 3 mph (5 km/h), the foot brake must bepressed again to leave this position.
D - DriveIn this driving position, the forward gears areshifted automatically.
S - SportThe locking button must be pressed to shiftinto the selection range S. The controlmodule selects gears automaticallyaccording to a sporty characteristic curve.
+ and -The Tiptronic functions are performed in theright selector lever gate and at the steeringwheel paddles.

Selector Lever Design in 2005 Jetta
The selector lever activates the Multi-Function Transmission Range (TR) SwitchF125 via the selector lever linkage.Mechanical movement of the linkage isconverted by the Multi-Function TransmissionRange (TR) Switch F125 into electricalsignals corresponding to the selector leverposition. The electrical signals are sent overanalog wires to the Transmission ControlModule (TCM) J217.
Selector Lever Park Position Lock SwitchF319
If the selector lever is in the P position,the switch sends the signal selector leverin position P to the Steering ColumnElectronic Systems Control Module J527. Thecontrol module requires this signal to controlthe ignition key removal lock.
Shift Lock Solenoid N110
The Shift Lock Solenoid N110 is controlled bythe Transmission Control Module (TCM) J217.
Tiptronic Switch F189
The switch recognizes the Tiptronic gate aswell as Tip + and Tip -. The signal travels overan analog wire to the Transmission ControlModule (TCM) J217.
