Introduction
This manual provides detailed procedures necessary to diagnose, rebuild, and repair the AISIN TF60SN transaxle. This 6-speed, fully automatic, and electronically controlled transaxle is also known by Volkswagen's 09G/09M designation and BMW's 6F21WA for the Mini-Cooper. It is intended for automotive technicians familiar with automatic transmission operation.
The TF60SN transaxle is utilized across a wide range of applications and engine sizes, leading to variations in friction plates, planetary ratios, intermediate ratios, and final drive ratios based on specific vehicle torque load requirements.
Transmission Identification and Variations
The TF60SN transaxle is known by several designations including TF60-SN, 09G, 09M, 6F21WA, and sometimes 09K in overseas vehicles. Due to its broad application, various case and part configurations exist. This manual highlights these differences to prevent incorrect part usage and potential severe planetary failure.
- Heat Exchanger Configurations: Some units feature a heat exchanger attached directly to the transmission, while others use a remote heat exchanger. This distinction affects the case, case cover, and valve body.
- Gear Ratio Sensitivity: The TF60SN system is gear ratio sensitive, necessitating correct transaxle interchange for proper function.
Careful identification of the specific transaxle configuration is paramount before commencing any rebuild or repair work.
