Timing solenoid valve
CAUTION!
• Do not insert air gun against strainer
installed on inlet of solenoid valve too
deeply, when blowing air into solenoid
valve. If not, the strainer will be damaged.
• Be very careful as dust etc. does not enter
when solenoid valves are inspected.

• Check that solenoid valve (1) actuate with click sound
when battery voltage is conducted.
• When timing solenoid valve (1) is connected to battery
(2), confirm that timing solenoid valve is open
condition by blowing air (50 – 200 kPa, 0.5 – 2.0 kg/
cm
2, 7 – 28.5 psi) into solenoid valve as shown in
figure.
• When timing solenoid valve (1) is not connected to
battery (2), confirm that timing solenoid valve is close
condition by blowing air (50 – 200 kPa, 0.5 – 2.0 kg/
cm
2, 7 – 28.5 psi) into solenoid valve as shown in
figure.
NOTE
Do not fail to inspect with air to prevent
mistaken checking because return spring for
valve is not installed into solenoid valve.

9) Remove fluid cooler pipes (1) and pipe unions (2).
10) Remove fluid level gauge (3) and fluid filler tube (4).
11) Remove oil pan (1) and oil pan gasket (2).
NOTE
• For removal of oil pan, do not turn
transaxle over as this will contaminate
valve body with foreign materials in
bottom of oil pan.
• When removing oil pan, tap around it
lightly with plastic hammer. Do not force it
off by using screwdriver or the like.

12) Remove oil strainer assembly (1).13) Disconnect connectors (2) from solenoid valves and
transmission fluid temperature sensor (1).
14) Remove valve body assembly bolts.
CAUTION!
Be careful not to let manual valve fall off
when removing valve body assembly.

NOTE
There are five kinds of bolts (bolts A (1), B (2),
C (3), D (4) and E (5)) fixing valve body
assembly.

15) Remove manual valve rod (1) from manual valve
lever (2), then remove valve body assembly (3).

16) Remove valve body harness (1).
CAUTION!
When pulling valve body harness out of
transaxle case, take care not to damage
transmission fluid temperature sensor (2) at
narrow exit of case.
Careless sensor treatment might cause
sensor malfunction.

17) Remove governor apply No.1 gasket (1).
18) Remove cooler check valve (1) and spring (2).19) Remove accumulator pistons and springs.
To remove C2 (1), C1 (2) and B1 (3) accumulator
pistons and springs, position rag on pistons to catch
each piston. To remove pistons, force low-pressure
compressed air (1 kg/cm
2, 15 psi, 100 kPa, max) into
hole (4) as shown in figure, and pop each piston into
rag.
NOTE
Do not push accumulator pistons with
fingers or anything before removing them.
Pushing them may cause compressed fluid
in accumulator to spew out of hole and get to
your face and clothes.

Valve Body Assembly Disassembly and
Reassembly
S6RW0D5106051
CAUTION!
When replacing pressure control solenoid
valve and/or TCC pressure control solenoid
valve, it is strictly required to replace it
together with valve body assembly as a set.
Replacing pressure control solenoid valve
and/or TCC pressure control solenoid valve
independently may cause excessive shift
shock.
