The 5-speed automatic Aisin AW55-51LE was produced at a plant in Japan from 2001 to 2011 and was installed on many popular General Motors crossovers under its own index AF33. In many markets, this gearbox is best known as the automatic transmission of the Chevrolet Captiva and Opel Antara.

Disadvantages of the Aisin AW55-51LE gearbox
- This is a reliable Japanese gearbox and it caused problems only in the first years.
- However, this version began to be installed en masse in 2006, already in an updated version.
- If you regularly renew the lubricant, its resource will easily exceed 300,000 km or more.
- In thrifty owners, the hydraulic unit becomes clogged with wear products from the torque converter clutch.
- Then the oil pump bushing usually breaks and noticeable oil leaks appear.
