5th gears).
Direct clutch control valve
Regulates line pressure to the optimum pressure (direct clutch pressure) to be
applied to the direct clutch when the direct clutch is coupled (regulates clutch
pressure in 2nd, 3rd, 4th gears).
Lock-up control valve
Lock-up control plug
Lock-up control sleeve
Switches lock-up to operating or released.
Also, by performing the lock-up operation transiently, lock-up smoothly.
Torque converter lubrication valve
Operates to switch torque converter, cooling, and oil path of lubrication system during
lock-up.
Cool bypass valve
Allows excess oil to by pass 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
Delivers line pressure to each circuit in response to each select position.
Circuit to which line pressure is not sent drain.
SUB ROM unit
1. Installing location: The valve body upper part
2. Function: To obtain A/T fluid pressure stability by compensating for solenoid&valve body unit fluid pressure differential.
3. Principle: Install additional ROM onto valve body of automatic transmission and input fluid pressure differential of solenoid
&valve body so that TCM reads the input data to perform fluid pressure compensation.
4. Maintenance
(1) When replacing with a new TCM in the vehicle
A. TCM automatically reads SUB ROM DATA during I.G ON. At this time, shift range valve is off for about 2.5 second.
(2) When replacing A/T (regardless of new or old ones) in the vehicle
