Installation
Remove removal procedure to install solenoid valves,
noting the following points.
• For details of solenoid valves and their connectors

installation, refer to “Automatic Transmission Unit
Assembly”. Use new O-ring.

• For details of A/T oil pan installation, refer to

“Automatic Transmission Unit Assembly”.

• Tighten exhaust No.1 pipe bolts & nuts and exhaust

bracket bolts & nuts.

• Fill A/T fluid and check fluid level according to

procedure described in “A/T Fluid Change”.

• Check for fluid leakage after warming up A/T.

Solenoid Valves (Shift Solenoid-A, Shift
Solenoid-B, Shift Solenoid-E, TCC Solenoid,
Pressure Control Solenoid-A, Pressure Control
Solenoid-B, and Pressure Control Solenoid-C)
Inspection

S6JB0B5106022

Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B
and Shift Solenoid-E)
Resistance check

CAUTION

!

Be very careful as dust etc. does not enter
when solenoid valves are inspected.

Measure resistance between terminal (2) and solenoid
valve body. If resistance is out of specification, replace
solenoid valve.

Shift solenoid-A, Shift solenoid-B and Shift solenoid-
E resistance
Standard: 11 – 15

Ω (at 20 °C (68 °F))

Operation Check
• With solenoid connected to battery (2) as shown in the

figure, check that solenoid valve is actuated with click
sound.

• With shift solenoid valve (1) connected to battery (2),

confirm that shift solenoid valve is open by blowing air
(50 – 200 kPa, 0.5 – 2.0 kg/cm

2

, 7 – 28.5 psi) into

solenoid valve as shown in the figure.

• With shift solenoid valve (1) not connected to battery

(2), confirm that shift solenoid valve is closed by
blowing air (50 – 200 kPa, 0.5 – 2.0 kg/cm

2

, 7 – 28.5

psi) into solenoid valve as shown in the figure.

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.

Pressure Control Solenoid Valves (Pressure Control
Solenoid-A, Pressure Control Solenoid-B, Pressure
Control Solenoid-C and TCC Solenoid Valve)
Resistance check

CAUTION

!

Be very careful as dust etc. does not enter
when pressure control solenoid valves are
inspected.

Measure resistance between pressure control solenoid
valves (Pressure control solenoid-A, Pressure control
solenoid-B, Pressure control solenoid-C and TCC
solenoid) (1) terminals. If resistance is out of
specification, replace valve body assembly.

Pressure control solenoid-A, Pressure control
solenoid-B, Pressure control solenoid-C and TCC
solenoid resistance
Standard: 5.0 – 5.6

Ω (at 20 °C (68 °F))

Operation check
Check pressure control solenoid valves (Pressure
control solenoid-A, Pressure control solenoid-B,
Pressure control solenoid-C and TCC solenoid) (1)
operation in either of the following methods.
[Using regulated DC power supply]

1) Connect pressure control solenoid valve (1) with

regulated DC power supply (2) as shown in the
figure.

2) Turn regulated DC power supply switch ON,

increase voltage of power supply keeping current
within 1.0 A.

3) Check that valve (3) moves gradually in arrow “A”

direction as voltage increases.

4) Check that valve (3) moves in arrow “B” direction as

voltage decreases.

5) Turn power supply switch OFF.

CAUTION

!

Do not feed current 1.0 A or more, or
pressure control solenoid will be burned out.

[Not using regulated DC power supply]

1) Connect pressure control solenoid valve (1) to

battery (4) setting 21 W bulb (2) in between as
shown in the figure.

2) Check that valve (3) moves in arrow “A” direction.
3) Disconnect pressure control solenoid valve (1) from

battery (4) and check that valve (3) moves in arrow
“B” direction as shown in the figure.

CAUTION

!

Set 21 W bulb in between, or pressure control
solenoid valve will be burned out.
