•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?
Ye s>>Go to step 5 for disc or plate abrasion.
No
>>Go to the next step.
3.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?
Ye s>>Go to the next step.
No
>>Replace damaged components and 2nd gear brake clutch and overdrive clutch for low pressure
burned.
4.COMPRESSED AIR TEST
• Check 2nd gear brake clutch system: 2nd gear brake clutch piston should be active and maintain pressure
when compressed 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?
Ye s>>Go to the next step for disc or plate abrasion.
No
>>Replace damaged components and 2nd gear brake clutch and overdrive clutch for low pressure
burned.
