Automatic Transaxle (Diagnostics): Other Subaru BRZ ZC

Precautions

Note. Reset memory operation is not completed just by disconnecting the battery cable.

1. Precautions for removal and installation procedures Since the automatic transmission consists of parts with a very precise finish, careful inspection is required before assembling these parts. Even a small scratch may cause liquid leakage or affect the performance. Instructions in this chapter are organized so that the work for only 1 component group is performed at a time. This is to avoid confusion which can occur when parts having similar appearance but for different SUB-ASSY exist in the same workbench at the same time. Inspect and repair the component group from the converter housing side. Try to complete the inspection, repair, or assembly work before proceeding to the next component group. If any defect is found in a specific component group during assembly, immediately check and repair the group. When a component group cannot be assembled due to the parts order, be sure to store all parts of the group in another container while another component group is being disassembled, checked, and assembled. The auto fluid (ATF) WS is recommended. Wash all of the removed parts and blow through all of the liquid passages and holes with compressed air. Dry all parts with compressed air. Never dry the parts using rugs and cloths in the work area. When using compressed air, do not point the air outlet toward you to prevent auto fluid and detergent from being blown to your face by mistake. Use only the recommended automatic transmission fluid or appropriate detergent for cleaning. After washing, arrange the parts in the correct order for efficient inspection, repair, and assembly. When removing the valve body, be sure to keep each valve with the corresponding spring. Soak new discs (for replacement) of the brake and clutch in ATF for at least 15 minutes before the assembly. Before the assembly, apply ATF to all of the oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces. Replace all gaskets and rubber O-rings with new parts. Do not apply adhesive cement to gaskets and similar parts. Check that the both ends of the snap ring do not overlap the notch and the snap ring is installed in the groove correctly. When replacing a worn bushing, be sure to replace the SUB-ASSY including the bushing. Check for wear and damage of the thrust bearing and race. Replace them as required. Observe the following precautions when handling FIPG material. Completely remove the old sealant (FIPG) material from the gasket surface using a razor or gasket scraper. Carefully clean all the components and remove materials that are coming off. Clean the both surfaces of the seal with appropriate detergent. The parts must be assembled within 10 minutes after sealant (FIPG) is applied. If it is impossible, remove the sealant (FIPG) material and apply it again.
