• In accordance with the shown status of standard fluid pressure measurement table, measure the fluid pressure

of each measurement port. The measurement of each port should be within the standard range.

• If some measurement values is beyond the standard range, please refer to the fluid pressure measurement and

diagnosis table for causes.

Is the check result normal?

Yes

Go to step 5 for disc or plate abrasion.

Go to the next step.

CHECK VALVE BODY ASSEMBLY AND FLUID PUMP AND PIPELINE

• Turn the ignition switch off.

• Disassemble and repair F4A4 automatic transaxle assembly (See Automatic Transaxle Removal & Installation in

Section 08 Transaxle & Transfer Case).

• Check valve body and fluid pump and pipeline.

Is the check result normal?

Yes

Go to the next step.

Replace damaged components and low speed clutch and overdrive clutch for low pressure burned.

COMPRESSED AIR TEST

• Check low speed clutch system: Low speed clutch piston should be active and maintain pressure when com-

pressed air is applied to the fluid hole.

• Check overdrive clutch system: Overdrive clutch piston should be active and maintain pressure when com-

pressed air is applied to the fluid hole.

Is the check result normal?

Yes

Go to the next step for disc or plate abrasion.

Replace damaged components and low speed clutch and overdrive clutch for low pressure burned.

DIAGNOSIS & TESTING

CHECK LOW SPEED CLUTCH SYSTEM

• Stop vehicle and turn ignition switch off.

• Disassemble and repair F4A4 automatic transaxle assembly (See Automatic Transaxle Removal & Installation in

Section 08 Transaxle & Transfer Case).

• Check low speed clutch system:

− Check low speed clutch plate
− Check low speed clutch disc
− Snap ring
− Clutch reaction disc
− D-Ring
− Spring retainer
− Low speed clutch piston
− Low speed clutch drum

Is the check result normal?

Yes

Go to the next step.

Replace the damaged components.

CHECK OVERDRIVE CLUTCH SYSTEM

• Check overdrive clutch system:

− Check overdrive clutch plate
− Check overdrive clutch disc
− Central support
− Snap ring
− Clutch reaction disc
− Spring retainer
− Overdrive clutch piston

Is the check result normal?

Yes

Go to the next step.

Replace the damaged components.

CHECK DTC

• Assemble all disassembled components.

• Install the transaxle assembly (See Automatic Transaxle Removal & Installation in Section 08 Transaxle &

Transfer Case).

• Fill the transaxle with new ATF:

− Fill the ATF from the fill tube.
− Reinstall the hose connector disassembled in step 1 and reinstall the dipstick (clean the dipstick before

installing).

− Shift the gear selector lever to each gear position and then shift to gear “N”.
− Drive the vehicle until the ATF reaches operating temperature (70° - 80°C) and re-check the fluid level. The

fluid level must be within the HOT range of dipstick.

− Reinstall the dipstick into the transaxle.
− With the X-431 scan tool, read TCM DTCs.
− Refer to

⬙DTC Confirmation Procedure⬙.

Is DTC 43 present?

Yes

Replace the TCM.

The system is now operating properly.

POSSIBLE CAUSES

Fourth gear, ratio

out of limits

Vehicle is driving

• The Transaxle
Control Module
(TCM) will set this
DTC when the TCM
detected that 4th
Gear Ratio Error is
already present. The
output shaft speed
signal is increased.

• If the DTC was
set 4 times, then the
A/T will be locked in
3rd gear (D gear).

• Input shaft speed
sensor

• Output shaft speed
sensor

• The retainer of
deceleration clutch

• Transfer case
driven and drive gear

• Low speed clutch
system

• Overdrive clutch
system

• 2nd brake system

• Noise interference

DTC Confirmation Procedure:

Before performing the following procedure, confirm that battery voltage is more than 12 V.

• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
