Components of the AW55 automatic transaxle

Design:

The gear ratios are achieved by means of a combined planetary gear set on the input side and a Simpson set on the output side.

• The combined planetary gear set consists of two different, simple planetary gear sets. It has a similar structure to a Ravigneaux set, but with just one sun gear that engages with the front planetary gears.
• Three multi-plate clutches
• Four multi-plate brakes
• One band brake
• Two one-way clutches

The TCM adapts the gear changing to ensure that the correct gear is selected for the style of driving, the engine load, driver requirements, vehicle speed etc.

The TCM features a self-learning strategy.

This leads to lower fuel consumption together with improved comfort through smoother gear changes and lower noise levels.
