Suzuki Grand Vitara JB416 / JB420 / JB419. Manual — part 327
5A-99 Automatic Transmission/Transaxle:
Operation check
Check pressure control solenoid valves (Pressure
control solenoid and TCC pressure control 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.
Transmission Fluid Temperature Sensor
Removal and Installation
S6JB0A5106023
Removal
1) Disconnect negative cable at battery.
2) Pull out fluid level gauge and lift up vehicle.
3) Remove drain plug and drain A/T fluid.
4) Install drain plug with new gasket.
5) Remove oil filler tube (2) and A/T oil pan (1).

6) Remove A/T oil strainer (1).
7) Disconnect shift solenoid–A connector (1), shift
solenoid–B connector (2), TCC pressure control
solenoid connector (4) and Pressure control solenoid
connector (3).
8) Remove solenoid valves.
9) After removing bolt (1) pull out transmission wire
connector (2) from transmission case.
CAUTION
!
When pulling transmission wire harness out
of transmission case, take care not to
damage connectors and transmission fluid
temperature sensor at narrow exist of case.
Careless sensor treatment might cause
sensor malfunction.
Installation
Remove removal procedure to install transmission fluid
temperature sensor, 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”.
• 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.
• Tighten transmission wire connector bolt to specified
torque referring to “Automatic Transmission Unit
Assembly”.
Transmission Fluid Temperature Sensor
Inspection
S6JB0A5106024
Immerse transmission fluid temperature sensor (1) in
water or oil. Check transmission fluid temperature
sensor resistance between terminals of connector. Thus
make sure its resistance decreases as temperature
rises.
If sensor resistance is out of specification, replace
solenoid wire harness (2).
Transmission fluid temperature sensor resistance

5A-101 Automatic Transmission/Transaxle:
Transmission Control Module (TCM) Removal
and Installation
S6JB0A5106025
CAUTION
!
TCM consists of highly precise parts, so
when handling it, be careful not to expose it
to excessive shock.
Removal
1) Disconnect negative cable at battery.
2) Disable air bag system.
Refer to “Disabling Air Bag System in Section 8B”.
3) Remove glove box.
4) Disconnect connectors from TCM (1).
5) Remove TCM with 4WD control module by removing
its nuts, and then separate TCM and 4WD control
module.
Installation
Reverse removal procedure noting the following points.
• Connect TCM connectors securely.
• Be sure to enable air bag system after TCM is back in
place. Refer to “Enabling Air Bag System in Section
8B”.
A/T Relay Inspection
S6JB0A5106026
1) Disconnect negative cable at battery.
2) Remove integration relay No.2 (1) from fuse box
No.2 (2).
3) Check that there is no continuity between terminals
“E41-1” and “E38-8”.
If there is continuity, replace relay.
4) Connect battery positive (+) terminal to terminal
“E38-6” of relay. Connect battery negative (–)
terminal to terminal “E38-7” of relay. Check for
continuity between terminal “E41-1” and “E38-8”. If
there is no continuity when relay is connected to the
battery, replace integration relay No.2.
