The intermediate clutch works with the intermediate one-
way clutch to hold the reverse sun gear
stationary in second gear. The intermediate clutch remains applied in third and fourth gears, but does
not transmit power.
Clutch— Forward
The forward clutch couples the forward clutch cylinder and input shaft to the forward sun gear in first,
second, and third gears. The forward clutch is not applied in fourth gear. Item Part Number Description

The reverse clutch couples the input shaft to the reverse sun gear, applied in reverse range only.
One-
Way Clutch— Planetary (Low)
The planetary (low) one- way clutch is a roller clutch that holds the planetary gearset in first gear, (D)
and D ranges. During automatic coasting downshifts into first gear ((D) and D ranges), the planetary
one- way clutch freewheels so there is no engine braking.

The transmission uses a gerotor-
type design front pump support and gear. The pump provides the
volume of fluid needed to charge the torque converter, main control assembly, cooling system and
lube system. Pump pressure is regulated by the main regulator valve. The pump has an internal boost
circuit which is more efficient at lower engine speeds.
Filter
All fluid drawn from the transmission pan by the pump passes through the filter. The filter and its
accompanying seal are part of the fluid path from the sump (pan) to the fluid pump.
Main Control
The main control valve body houses three electronic solenoids:
ztwo shift solenoids
z one torque converter clutch solenoid (TCC solenoid) Accumulators 1 — Outer rotor (part of 7A103)
2 — Inner rotor (part of 7A103)
3 — Outlet
4 — Inlet
Item Part Number Description
1 — Shift solenoid A (part of 7G484)
2 7G136 Torque converter clutch solenoid
3 — Shift solenoid B (part of 7G484) Klj . 2 ba
