The coast clutch is a multi-disc clutch made up of steel and friction plates.
- The coast clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
- The coast clutch is housed in the overdrive drum.
- The coast clutch is applied when in manual 1st and 3rd, 4th with OD cancelled, and REVERSE positions.
- When applied, the coast clutch locks the overdrive sun gear to the overdrive planetary carrier, thus preventing the one-way clutch from overrunning when the vehicle is coasting.
- This allows the use of engine compression to help slow the vehicle and provide engine braking.
