How does a clutch work in an automatic transmission?

Each clutch in an automatic transmission is put into motion using pressurized hydraulic fluid. When the pressure drops, springs cause the clutch to release. Evenly spaced ridges, called splines, line the inside and outside of the clutch to lock into the gears and the clutch housing.

How long does a automatic clutch last?

Most clutches are designed to last approximately 60,000 miles before they need to be replaced. Some may need replacing at 30,000 and some others can keep going well over 100,000 miles, but this is fairly uncommon.
