Mazda 3 Service Manual: Coupler Component Removal/Installation [Fw6 A EL]

WARNING:

• A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool.

• Always wear protective eye wear when using the air compressor. If the air compressor is used, any particles of dirt or soiling could spatter and get into the eyes.

CAUTION:

• Do not place the control valve body connector pointed downward as the control valve body connector part and sensor could be damaged. If the servicing can only be performed by pointing the control valve body connector downward, spread a large quantity of cloth or sponges on a table and place the control valve body connector part and sensor on the table so that they do not directly contact the table.
