ATSG Tech Manual 09D TR60SN VW Porsche Audi Repair Rebuild Book
ATSG (Automatic Transmission Service Group) VW 09D / TR60SN Techtran Rebuild Guide Repair Manual.
The Japanese company AISIN Co., LTD is the manufacturer and developer of the Rear Wheel Drive TR60SN transmission, which is a 6 speed, fully automatic and electronic controlled transmission.
Volkswagen engineers were also involved, in conjunction with Aisin, in the development process for their vehicles and Volkswagen gave it the "09D" designation. The TR60SN, 09D transmission is used in a wide variety of applications and engine sizes. As a result, the number of friction plates, and planetary gears (3 or 4 pinion), will vary depending on torque load requirements of the specific vehicle. The TR60SN transmission uses a gear ratio sensitive system, requiring the correct transmission interchange.
The TR60-SN (09D) is currently used in the:
- Porsche Cayenne
- Volkswagen Touareg (09D)
- Audi Q7
The 09D transmission uses a Lepelletier arrangement, using a simple planetary coupled with a Ravigneaux type, dual planetary. This is the same type of gear set that was used in the FMX. This arrangement makes six forward speeds and reverse possible, with only five clutch packs and one freewheel.
This manual contains the procedures necessary to diagnose, rebuild and/or repair the TR60SN "09D" transmission and is intended for automotive technicians that are familiar with the operation of automatic transmissions.
