Automatic Transmission/Transaxle: Service Precautions

Precaution
The following are precautions that must be followed performing removal/installation.

1. Handle electronic parts with care
^ Do not pull the wiring harness forcibly when disconnecting the connector. Unlock the first and pull the connector.
^ When connecting the connector, verify that it is inserted until it is properly locked. (Verify that a click sound is heard.)
^ Do not apply shock to electronic parts. Replace with new parts if they have been dropped or subjected to shock.
2. Prevent foreign matter from penetrating
^ Be sure to remove foreign matter such as dust and sand from the automatic transaxle before removing parts.
^ Protect removed parts from dust with an object such as a vinyl sheet.
^ Do not use cotton work gloves or shop rags as frayed strings might get caught in the unit. Work with bare hands or use vinyl gloves.
3. Prevent scratching
^ Do not pry with a screwdriver forcibly. Slightly tap the case with a plastic hammer when separating component cases at seams.
^ Do not pull the valve forcibly.
^ Be careful not to get the wiring harness caught between parts during installation.
4. Prevent incorrect or insufficient, installation or missing parts
^ Be careful not to install parts incorrectly or lose parts since there are similar types of O-rings, snap rings, bearings and races. Be careful to for straighten parts and check their installation direction.
^ Be careful not to drop small parts such as check balls or lose them during installation.
5. Wash parts and apply oil
^ Wash each part before installing and dry using compressed air, and then apply the specified ATF type JWS3309.
^ Soak discs in ATF type JWS3309 before installing. In particular, soak a new disc for 2 h or more so that the oil seeps into the lining.
^ If the thrust bearing or race falls during installation, use a small amount of yellow petrolatum grease.
^ Apply ATF type JWS3309 to contact and rotating surfaces.
^ Do not apply oil or drive the vehicle immediately after installing a part applied with sealant. Leave it for one hour or more.
^ Do not wash aluminum parts or rubber parts with alkaline chemicals.
^ Do not wash rubber parts with isopropyl alcohol (IPA).
6. ATF care
^ If ATF is spilled on the floor, wipe it off immediately, as it is quite slippery and dangerous.
^ Be sure to use JWS3309 type ATF.
