The direct clutch is a multi-disc clutch made up of steel and friction plates.

• The direct clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
• It is housed in the intermediate brake and direct clutch drum.
• In drive, the direct clutch is applied and coupled to the forward clutch. This drives the input shell and forward sun gear in 4th and 5th gears.
• In reverse, the direct clutch is applied and coupled to the input shell and forward sun gear.
• This action causes the forward sun gear to drive the pinions of the reverse planetary carrier.
• Since the reverse planetary carrier is held stationary by the reverse band, the pinions drive the output shaft ring gear in reverse.
