CHANGE MECHANISM
The same select pattern shift lever is used as the floor type and
frequently used “N” and “D” ranges are made selectable freely. Throttle position
signal circuit
(DTC P1700)No or abnormal throt-
tle opening signal is
inputtedScheduling of automatic gear shift is performed as throttle
valve opening is 0%.
Control of automatic gear shift (i.e. control of oil pressure) is
performed as throttle valve opening is 100%.
Coast down shifting is performed when brake is applied and
engine rev. is less than 1,500 rpm.
Lock-up function is turned OFF.

2. DIAGNOSTIC TROUBLE CODE (DTC) CHECK, RECORD AND CLEARANCE
To check DTC, refer to “DTC CHECK” in this section. When a DTC exists, it means existence of a malfunction in
the system represented by that code but whether it still exists (current) or it occurred in the past and has gone
(history) is unknown. To know it, clear this DTC once (Refer to “DTC CLEARANCE” in this section.), perform
test drive and/or “TROUBLE SYMPTOM CONFIRMATION” in this section and then check DTC again as
described in “DTC CHECK”. Attempt to diagnose the trouble based on the DTC recorded in this step only or fail-
ure to clear the DTC in this step may mislead the diagnosis or make diagnosing difficult. Even after checking the
DTC with the SUZUKI scan tool, diagnosis should be performed according to this flow chart to check TCM for
proper self-diagnosis function.
3 and 4. VISUAL INSPECTION
As a preliminary step, perform visual check of the following items that support proper function of the automatic
transmission.
5.TROUBLE SYMPTOM CONFIRMATION
Check if what the customer claimed in “CUSTOMER COMPLAINT ANALYSIS” is actually found in the vehicle
and if that symptom is found, whether it is identified as a failure. (This step should be shared with the customer
if possible.)
When the symptom is not actually found, possibility is :
The symptom occurs under certain conditions.
----- Retry with the vehicle under different conditions.
The trouble occurred only temporarily and normal operation has been restored.
----- Perform “DTC CHECK” and if the diagnostic trouble code is indicated, inspect according to the flow
table for that DTC.
6 and 7. RECHECKING AND RECORD OF DTC
Refer to “DTC CHECK” in this section.INSPECTION ITEM REFERRING SECTION
Engine oil ----- level, leakage Section 0B
Engine coolant ----- level, leakage Section 0B
A/T fluid ----- level, leakage, color Section 0B

LINE PRESSURE TEST
Purpose of this test is to check operating conditions of each part
by measuring fluid pressure in fluid pressure line.
Line pressure test requires following conditions.
Automatic fluid is at normal operating temperature (70 –
80°C /158 – 176°F).
Fluid is filled to proper level (between FULL and LOW on
dipstick).
1) Apply parking brake securely and place chocks against
wheels.
2) Remove fluid pressure check hole plug bolt.
3) Attach oil pressure gauge to fluid pressure check hole in
transmission case.
Special tool
(A) : 09925-37811-001
4) Depress foot brake fully, run engine at idle and stall then check fluid pressure in “D” or “R” range.
Line pressureCAUTION:
After attaching oil pressure gauge, check that no fluid
leakage exists.

Do not continue running engine at stall speed longer than 5 seconds.

FLUID LEVEL AT ROOM TEMPERATURE
INSPECTION
The fluid level check at room temperature performed after repair
or fluid change before test driving is just preparation for level
check of normal operation temperature. The checking procedure
itself is the same as that described previously. If the fluid level is
between FULL COLD and LOW COLD, proceed to test drive. And
when the fluid temperature has reached the normal operating
temperature, check fluid again and adjust it as necessary.
FLUID CHANGE
1) Lift up vehicle.
2) When engine has cooled down, remove drain plug (1) from
oil pan and drain A/T fluid.
3) Install drain plug.

DISASSEMBLY/ASSEMBLY OF SUBASSEMBLY
OIL PUMP
CAUTION:
 Keep component parts in group for each subassembly and avoid mixing them up.
 Clean all parts with cleaning solvent thoroughly and air dry them.
 Use kerosene or automatic transmission fluid as cleaning solvent.
 Do not use wiping cloths or rags to clean or dry parts.
 All oil passages should be blown out and checked to make sure that they are not obstructed.
 Keep face and eyes away from solvent spray while air blowing parts.
 Check mating surface for irregularities and remove them, if any, and clean it again.
 Soak new clutch discs and brake discs in transmission fluid for at least 2 hours before assembly.
 Replace all gaskets and O-rings with new ones.
 Apply automatic transmission fluid to all O-rings.
 When installing seal ring, be careful so that it is not expanded excessively, extruded or caught.
 Replace oil seals that are removed and apply grease to their lips.
 Before installing, be sure to apply automatic transmission fluid to sliding, rolling and thrusting sur-
face of all component part. Also after installation, make sure to check each part for proper opera-
tion.
 Always use torque wrench when tightening bolts.
