The Aisin AW72-41LE 4-speed automatic was produced at a plant in Japan from 2002 to 2009 and was installed exclusively in the Pontiac Vibe, paired with the 1.8-liter 1ZZ-FE and 2ZR-FE engines. This automatic transmission is essentially a variant of the Toyota A246E.

Disadvantages of the Aisin AW72-41LE gearbox
- This is a very reliable Japanese automatic transmission, and its only weak point is the wiring;
- Because of this, you may occasionally encounter failures of the solenoids or the gear selector;
- The torque converter lockup clutch lasts a long time, and when it wears out, it leaks at the oil seal;
- Closer to 250,000 km, the rear output shaft support bearing often requires replacement;
- And if you drive with a worn bearing, the rear planetary gearset will break.
