AUTOMATIC TRANSMISSION (4 A/T) 7B1-41
Manual Road Test
This test check the gear being used in “L”, “2” or “D” range when
driven with unoperated gear shift control system. Test drive vehi-
cle on a level road.
1) Disconnect shift solenoid coupler (1) valves on transmission.
2) With select lever in “P”, start engine and warm it up.
3) With select lever in “L” range, start vehicle and accelerate to
20 km/h (12.5 mile/h). Check in this state that 1st gear is
being used.
4) At 20 km/h (12.5 mile/h), shift select lever to “2” range and
accelerate to 40 km/h (25 mile/h). Check in this state that 3rd
gear is being used.
5) At 40 km/h (25 mile/h), shift select lever to “D” range and
check that O/D gear is used when speed is higher than 40
km/h (25 mile/h).
6) After above checks, stop vehicle then engine, and connect
shift solenoids coupler (1) with ignition switch OFF.
7) Clear DTC with scan tool.
Time Lag Test
This test is to check conditions of clutch, reverse brake and fluid pressure. “Time lag” means time elapsed since
select lever is shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels respectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from “N” to “D” range and measure time from that moment till shock
is felt.
4) Similarly measure time lag by shifting select lever from “N“ to “R” range.
Specification for time lag :NOTE:
Before this test, check diagnostic trouble code (DTC).
WARNING:
To avoid the danger of being burned, do not touch the hot
exhaust system when disconnecting shift solenoid cou-
pler (1).

TROUBLESHOOTING
Engine Brake Test
1) While driving vehicle in 3rd gear of “D” range, shift select lever down to “2” range and check if engine brake
operates.
2) In the same way as in step 1, check engine brake for operation when select lever is shifted down to “L”
range.
3) If engine brake fails to operate in above tests, possible causes for such failure are as follows. Check each
part which is suspected to be the cause.
TROUBLESHOOTING
“P” Range Test
1) Stop vehicle on a slope, shift select lever to “P” range and at the same time apply parking brake.
2) After stopping engine, depress brake pedal and release paring brake.
3) Then, release brake pedal gradually and check that vehicle remains stationary.
4) Depress brake pedal and shift select lever to “N” range.
5) Then, release brake pedal gradually and check that vehicle moves.NOTE:
When repeating this test, be sure to wait at least minute after select lever is shifted back to “N”
range.
Engine should be warmed up fully for this test.
Condition Possible cause
When “N” → “D” time lag exceeds specification•Low line pressure
•Worn forward clutch
When “N” → “R” time lag exceeds specification•Low line pressure
•Worn direct clutch
•Worn reverse brake
WARNING:
Before test, make sure that there is no vehicle behind so as to prevent rear-end collision.
Condition Possible cause
Fails to operate when shifted down to “2” range Second coast brake defective
Fails to operate when shifted down to “L” range Reverse brake defective
WARNING:
Before test, check to make sure no one is around vehicle or down on a slope and keep watchful for
safety during test.

Fluid level
LEVEL CHECK AT NORMAL OPERATING TEMPERATURE
1) Stop vehicle and place it level.
2) Apply parking brake and place chocks against wheels.
3) With selector at P position, start engine.
4) Warm up engine till fluid temperature reaches normal oper-
ating temperature (70 – 80 °C (158 – 176 °F)). As a guide to
check fluid temperature, warm up engine till engine coolant
temperature meter indicated around 1 unit above “C” point.
5) Keep engine idling and shift selector slowly to “L” and back
to “P” position.
6) With engine idling, pull out dipstick, wipe it off with a clean
cloth and put it back into place.
7) Pull out dipstick again and check fluid level indicated on it.
Fluid level should be between FULL HOT and LOW HOT. if it
is below LOW HOT, add an equivalent of DEXRON
®-III up to
FULL HOT.
Fluid specification :
An equivalent of DEXRON
®-III
[A] : Shift the select lever with its button pushed in.
[B] : Shift the select lever without pushing its button.
NOTE:
DO NOT RACE ENGINE while checking fluid level, even
after the engine start.
DO NOT OVERFILL. Overfilling can causes foaming
and loss of fluid through breather. Then slippage and
transmission failure can result.
Bringing the level from LOW HOT to FULL HOT
requires 0.3 liters (0.64/0.53 US/lmp.pt).
If vehicle was driven under high load such as pulling a
trailer, fluid level should be checked about half an hour
after it is stopped.

4WD Control System Inspection
1) Install special tool to air hose connecting between air pump
assembly and differential (actuator) as shown in figure.
Tighten adjusting screw (2) of special tool as far as it stops.
Close air check side opening by using fuel hose (1) as blind
plug.
Special tool

SUZUKI GENUINE PARTS
(B) : 09367-04002
2) Turn ON ignition switch and shift transfer lever from 2H to 4H
range.
3) Check that motor starts running (a sound can be heard)
within 1 second and it stops when gauge of special tool indi-
cates specified pressure value.
Check also for air leakage.

Precaution for Maintenance Service
•When having driven through water, check immediately if
water has entered (if so, oil is cloudy). Water mixed oil must
be changed at once.
•Whenever vehicle is hoisted for any other service work than
oil change, also be sure to check for oil leakage and status of
breather hoses.
Differential Gear Oil Change
1) Before oil change or inspection, be sure to stop engine and
lift up vehicle horizontally.
2) Check oil level and existence of leakage. If leakage is found,
correct its cause.
3) Drain old oil and pour proper amount of gear oil as specified
(roughly up to level hole).
4) Torque drain plug (3) and level/filler plugs (2) to specification.

•As shown in the figure, use a 12 V battery to connect its (+)
terminal to terminal “A”, and its (–) terminal to “Black” lead
wire (2).
If motor (1) rotates at a low revolution speed of 45 to 55 rpm,
it is proper. For high speed check, connect battery (+) termi-
nal to terminal “B”, and its (–) terminal to “Black” lead wire
(2). If motor rotates at a high revolution speed of 67 to 83
rpm, it is proper.
•Testing automatic stop action.
a) Connect 12 V battery (+) terminal to terminal “A” of wiper
motor and (–) terminal to Black lead wire (2) and let the
motor turn.
b) Disconnect terminal “A” from battery, and let the motor
stop.
c) Connect terminal “A” and “D” with a jumper wire (3), and
connect terminal “C” to battery (+) terminal. Observe the
motor turns once again then stops at a given position.
d) Repeat a) through c) several times and inspect if the motor
stops at the given position every time.
