What is the multiplate clutch on a planetary gear set?
The multiplate clutch connects two rotating components of the planetary gear set. The two multiplate clutches are the forward clutch and the direct / reverse clutch. Each is made up of a clutch drum which is splined to accept the input shaft and turning torque from the engine. The drum also provides the bore for the clutch piston.
What kind of holding device does one way clutch use?
A one way clutch is a holding device which requires no seals or hydraulic pressure to apply. They are either a roller clutch or sprag clutch. Both operate in a way that they rely on wedging metal between two races. A one way sprag clutch consists of a hub as an inner race and a drum, or outer race.
Why does my solenoid stick in overdrive all the time?
NO, it was the fault of “some’at or other”, but being as they are quite strong they usually survive! Just saying, quite often the solenoid may misbehave in the J type and it sticks IN overdrive. It’s a right proverbial pain.
What are the holding devices for planetary gear sets?
The brake band takes very little space in the cavity of the transmission housing and has a large surface area to create strong holding forces. One way clutches are small in size and release and apply quickly, giving good response for upshifts and downshifts. The multiplate clutch connects two rotating components of the planetary gear set.
What does overrunning clutch mean in planetary gears?
Overrunning Clutch: A clutch mechanism that will drive in one direction only. If driving torque is removed or reversed the clutch slips. Also referred to as a one way clutch. Planet Gears: The gears in a planetary gear set that are in mesh with both the ring gear and the sun gear.
What happens when the direct clutch is disengaged?
Direct clutch is disengaged, allowing the direct clutch drum, annulus and output shaft to spin at a different rate from the sun gear and sliding hub. With the sun gear not rotating, power is transmitted from the intermediate shaft into the planetary gear set.

How does the overdrive clutch work on a Dodge?
Overdrive steels are splined to the case; the overdrive clutches are splined to the sliding hub. With the overdrive clutch engaged, the sliding hub stops turning, which is splined to the sun gear which also stops turning.
