Multi-Plate Clutch

Clutches; overdrive (4, 5, 6), forward (1, 2, 3, 4) and direct (3, 5, R) are balanced in terms of dynamic pressure. That is, their pistons are exposed to the transmission fluid flow on both sides to prevent pressure buildup in the clutch as speed increases. This dynamic pressure equalization process is achieved by a baffle plate and pressure-free transmission fluid supply by a lubricating passage, through which the space between the piston and baffle plate is filled with transmission fluid.

The advantages of this dynamic pressure equalization are:

• reliable clutch engagement and release in all speed ranges.
• improved shift refinement.
