ATF pressure switch 2 (LC/B)

Detects any malfunction in the low coast brake hydraulic pressure. When it detects any
malfunction, it puts the system into fail-safe mode.

Torque converter regulator valve

In order to prevent the pressure supplied to the torque converter from being excessive,
the line pressure is adjusted to the optimum pressure (torque converter operating pres-
sure).

Pressure regulator valve
Pressure regulator plug
Pressure regulator sleeve

Adjusts the oil discharged from the oil pump to the optimum pressure (line pressure) for
the driving state.

Front brake control valve

When the front brake is coupled, adjusts the line pressure to the optimum pressure
(front brake pressure) and supplies it to the front brake. (In 1st, 2nd, 3rd, and 5th gears,
adjusts the clutch pressure.)

Accumulator control valve

Adjusts the pressure (accumulator control pressure) acting on the accumulator piston
and low coast reducing valve to the pressure appropriate to the driving state.

Pilot valve A

Adjusts the line pressure and produces the constant pressure (pilot pressure) required
for line pressure control, shift change control, and lock-up control.

Pilot valve B

Adjusts the line pressure and produces the constant pressure (pilot pressure) required
for shift change control.

Low coast brake switching valve

During engine braking, supplies the line pressure to the low coast brake reducing valve.

Low coast brake reducing valve

When the low coast brake is coupled, adjusts the line pressure to the optimum pressure
(low coast brake pressure) and supplies it to the low coast brake.

N-R accumulator

Produces the stabilizing pressure for when N-R is selected.

Direct clutch piston switching valve

Operates in 4th gear and switches the direct clutch coupling capacity.

High and low reverse clutch control valve

When the high and low reverse clutch is coupled, adjusts the line pressure to the opti-
mum pressure (high and low reverse clutch pressure) and supplies it to the high and
low reverse clutch. (In 1st, 3rd, 4th and 5th gears, adjusts the clutch pressure.)

Input clutch control valve

When the input clutch is coupled, adjusts the line pressure to the optimum pressure (in-
put clutch pressure) and supplies it to the input clutch. (In 4th and 5th gears, adjusts the
clutch pressure.)

Direct clutch control valve

When the direct clutch is coupled, adjusts the line pressure to the optimum pressure
(direct clutch pressure) and supplies it to the direct clutch. (In 2nd, 3rd, and 4th gears,
adjusts the clutch pressure.)

TCC control valve
TCC control plug
TCC control sleeve

Switches the lock-up to operating or released. Also, by performing the lock-up operation
transiently, lock-up smoothly.

Torque converter lubrication valve

Operates during lock-up to switch the torque converter, cooling, and lubrication system
oil passage.

Cool bypass valve

Allows excess oil to bypass cooler circuit without being fed into it.

Line pressure relief valve

Discharges excess oil from line pressure circuit.

N-D accumulator

Produces the stabilizing pressure for when N-D is selected.

Manual valve

Sends line pressure to each circuit according to the select position. The circuits to which
the line pressure is not sent drain.
