The TR60-SN (09D according to VAG) is an innovative 6-speed automatic transmission designed by Aisin and released in 2003 for RWD Porsche Cayenne equipped with a 4-liter engine.

This transmission was designed simultaneously with the first 6-speed automatic transmission for FWD cars - TF60-SN and was tested since 2001 on a 2-liter Altezza

This transmission was supposed to be a leader in the world of luxury brands such as Porsche, Audi, Lexus and become a competitor to the new 6-speed ZF6HP transmission. Audi use 09D for Q7 SUVs with diesel engines from 3 to 4.2 liters.

EAW TR-60SN has been successfully used since 2007 in powerful (over 4.6l) RWD and AWD Lexus and Land Cruiser SUVs. There are several sub-modifications of this transmission for its torque class, differing in planetary gears, quantity of clutches and steel discs, the size of some of the units and parts. It was replaced by the 8-speed transmission TR80-SD.

This transmission was designed by the Aisin to become "invincible", like all of its RWD automatic transmission. But each automaker customized its TCM (transmission computer) in "democratic" fashion, enabling drivers to use its capacities to the fullest extent.

Technical issues and repair guidelines

The repair kit of gaskets and seals is always ordered with filters for reassembly procedure. It is usually ordered for changing teflon rings which must be changed to save friction components and the pump with solenoids. If the car is used with worn out teflon rings, then the friction elements get burnt and the rubber seals get harder because of the temperature.The overhaul is always accompanied by the replacement of burnt frictions and steel disks for K1, K2, B1 clutches. The reason is usually related to clogged valve body, solenoids, and seals. It is expressed in slippage of clutches under load or delays with shifting of gears.


The most problematic components of 09D:
  • The main problem of 09D installed in Volkswagen is related to clogging and breakdown of the hydraulic clutch plate with solenoids caused by ATF overheating and burning of the hydraulic clutch friction lining.
  • The torque converter is usually handed in for repair in order to replace worn-out clutch lock-up.
  • The wiring of solenoids often causes some malfunction. Older transmissions are provided with external fine filter.
  • Valve bodies for Tuareg are often handed in for repair.

For these transmissions it is recommended to take measures on improving the transmission cooling system, for example, by installing an additional radiator. It is also advised to check the ATF condition and change it as soon as it gets darker and loses transparency.
