Gearbox Aisin TR-60SN

The Aisin TR-60SN 6-speed automatic transmission was assembled in Japan from 2001 to 2011 and was installed on all-wheel drive Toyota and Lexus models with particularly powerful V8 engines. In some markets this transmission is known as the AL750 or the Porsche Cayenne and Volkswagen Touareg automatic transmission.

In 2001, the Japanese concern Aisin introduced a new 6-speed automatic transmission for all-wheel drive vehicles with particularly powerful engines up to 750 Nm of torque. By design, it is a hydromechanical automatic transmission with a Lepeletier planetary mechanism, which has five clutch packs: three clutches, two brakes, and an overrunning clutch. This automatic transmission is most widespread on VAG models under the symbol AL750 or 09D.

Gear ratios Aisin TR-60SN

Using the example of a Porsche Cayenne S 2008 with a 4.5 liter engine:

Main 4.100

  • Volkswagen Touareg 1 (7L) in 2002 – 2010.

Disadvantages of the TR-60SN gearbox

  • In the gearboxes of the first years of production, the solenoids could fail by 100,000 km, but the manufacturer quickly corrected itself: in 2005, a more reliable valve body appeared.
  • This is a strong automatic transmission with a decent service life, but its weak point is the thermostat: it often fails, the oil leaks in a small circle and the automatic transmission simply starts to overheat.
  • The oil pump here is very reliable, but when installing the torque converter there is a nuance: if you do not get the splines into the gear drives, it will crack and damage the pump housing.
  • On specialized forums, people regularly complain about oil leaks through electrical connectors, which have to be replaced.
