A/T CONTROL SYSTEM
Name
Function
TCM
Input clutch solenoid valve
Front brake solenoid valve
Direct clutch solenoid valve
High and low reverse clutch solenoid valve
Low coast brake solenoid valve
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.
PNP switch
Vehicle speed sensor A/T (Revolution sen-
sor)
