Durango 2WD V8-4.7L VIN N (2001)
Three hydraulically applied multi-disc clutches are used to hold some planetary geartrain components stationary while the input clutches drive others.
The 2C, 4C, and Low/Reverse clutches are considered holding clutches. The 2C and 4C clutches are located in the 4C retainer/bulkhead (Fig. 64),
while the Low/ Reverse clutch is located at the rear of the transmission case (Fig. 65).
OPERATION
2C CLUTCH
The 2C clutch is hydraulically applied in second gear by pressurized fluid against the 2C piston. When the 2C clutch is applied, the reverse sun gear
assembly is held or grounded to the transmission case by holding the reaction planetary carrier.
4C CLUTCH
The 4C clutch is hydraulically applied in second prime and fourth gear by pressurized fluid against the 4C clutch piston. When the 4C clutch is
applied, the reaction annulus gear is held or grounded to the transmission case.
LOW/REVERSE CLUTCH
The Low/Reverse clutch is hydraulically applied in park, reverse, neutral, and first gear, only at low speeds, by pressurized fluid against the
Low/Reverse clutch piston. When the Low/Reverse clutch is applied, the input annulus assembly is held or grounded to the transmission case.
