NO. 32 ATF SEEPING INTO AUTOMATIC TRANSAXLE (FS5A-EL) DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	INSPECT ATF FOR MALFUNCTION Inspect the ATF for the following: (See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION .) ATF condition ATF level Is the ATF normal?	Yes	Go to the next step.
1		No	Repair or replace the ATF level. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT .) NOTE: If the ATF level is less than the specified value, add ATF and go to the next step.
2	VERIFY IF ATF SEEPING CAUSE IS FROM O-RING Is the ATF seeping location in the following part installation areas? VSS Input/turbine speed sensor Oil filler tube End cover Parking rod lever component	Yes	Go to the next step.
2		No	Go to Step 4.
3	INSPECT PART INSTALLATION CONDITION FOR MALFUNCTION, Verify the part installation condition. Is there any installation bolt loosening or incorrect installation (Bolt is not seated to installation surface correctly)?	Yes	Installation bolt looseness: Tighten the bolt to the specified tightening torque. Incorrect installation: Replace the O-ring and install the parts correctly. (See AUTOMATIC TRANSAXLE - [FS5A-EL] -- MAZDA6 )
3		No	Replace the O-ring. (See AUTOMATIC TRANSAXLE - [FS5A-EL] -- MAZDA6 )
4	VERIFY IF ATF SEEPING CAUSE IS FROM WASHER Is the ATF seeping location in the following part installation areas? Oil pressure switch Connector pipe Connector bolt	Yes	Go to the next step.
4		No	Go to Step 7.
5	INSPECT PART INSTALLATION CONDITION FOR MALFUNCTION Verify the part installation condition. Is there any installation bolt loosening or incorrect installation (Bolt is not seated to installation surface correctly)?	Yes	Installation bolt looseness: Tighten the bolt to the specified tightening torque. Incorrect installation: Replace the washer and install the parts correctly. (See AUTOMATIC TRANSAXLE - [FS5A-EL] -- MAZDA6 )
5		No	Replace the washer. (See AUTOMATIC TRANSAXLE - [FS5A-EL] -- MAZDA6 )
6	VERIFY F ATF SEEPING CAUSE IS FROM OH. SEAL Is the ATF seeping location in the drive shaft oil seal?	Yes	Inspect the drive shaft (runout, damage on contact surfaces of drive shaft and oil seal). Repair the malfunctioning location, and then replace the oil seal. (See OIL SEAL REPLACEMENT .) (See AUTOMATIC TRANSAXLE - [FS5A-EL] -- MAZDA6 )
6		No	Go to the next step.
7	VERIFY IF ATF SEEPING CAUSE IS FROM SILICONE SEALANT Is the ATF seeping location in the following part installation areas? Oil pan End cover Mating surfaces of transaxle case and converter housing	Yes	Verify that there is no ATF seeping into the transaxle case around the seepage location. If leakage from the transaxle case is verified, replace the transaxle case. (See AUTOMATIC TRANSAXLE - [FS5A-EL] -- MAZDA6 ) If leakage from the transaxle case is not verified, re-apply the silicone sealant. (See CONTROL VALVE BODY REMOVAL/INSTALLATION .) (See )
7		No	Go to the next step.
8	VERIFY IF ATF SEEPING CAUSE IS FROM CONVERTER HOUSING OR ENGINE Is the ATF seeping location in mating surfaces of the converter housing and engine?	Yes	Inspect the following: Oil seal (torque converter) O-ring (oil pump) Repair the malfunctioning location. (See AUTOMATIC TRANSAXLE - [FS5A-EL] -- MAZDA6 )
8		No	Inspect the transaxle case for fissures or pin holes. If there is a malfunction, replace the transaxle case. (See AUTOMATIC TRANSAXLE - [FS5A-EL] -- MAZDA6 )
9	Verify test results. If normal, return to the diagnostic index to service any additional symptoms. If the malfunction remains, inspect the related Service Bulletins and/or On-line Repair Information and perform repair or diagnosis. If the vehicle is repaired, troubleshooting is completed. If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM.
