Disadvantages of the Aisin AW55-51LE gearbox
- This is a reliable Japanese transmission, and it only caused problems in the first few years;
- However, this version began to be installed en masse in 2006, already in an updated version;
- With regular lubricant changes, its service life will easily exceed 300,000 km or more;
- For frugal owners, the valve body becomes clogged with wear debris from the torque converter clutch;
- Then, the oil pump bushing usually breaks, and noticeable oil leaks appear.
