2004款丰田卡罗拉自动变速器系统维修手册(英文版) 40–1AUTOMATIC TRANSMISSION TRANS –AUTOMATIC TRANSAXLE ASSY ATMAUTOMATIC TRANSAXLE ASSY ATM400LF–01PRECAUTION1 The automatic transaxle is composed of highly precision–finished parts necessitating carefulinspection before reassembly because even a small nick could cause fluid leakage or affectthe performance The instructions here are organized so that youwork on only one componentgroup at a time This will help avoid confusion from similar–looking parts of different sub–as-semblies being on your workbench at the same time The component groups are inspected andrepaired from the converter housing side As much as possible complete the inspection repairand reassembly before proceeding to the next component group If a defect is found in a certaincomponent group during reassembly inspect and repair this group immediately If a compo-nent group cannot be assembled because parts are being ordered be sure to keep all parts ofthe group in a separate container while proceeding with disassembly inspection repair andreassembly of other component groupsRecommended ATF T–IV2 All disassembled parts should be washed clean and any fluid passages and holes should beblown through with compressed air3 Dry all parts with compressed air–never use shop rags4 When using compressed air always aim away from yourself to prevent accidentally sprayingATF or kerosene on your face5 The recommended automatic transaxle fluid or kerosene should be used for cleaning6 After cleaning the parts should be arranged in the correct order for efficient inspection repairsand reassembly7 When disassembling a valve body be sure to match each valve together with the correspond-ing spring8 New discs for the brakes and clutches that are to be used for replacement must be soaked inATF for at least 15 minutes before reassembly9 All oil seal rings clutch discs clutch plates rotating parts and sliding surfaces should becoated with ATF prior to reassembly10 All gaskets and rubber O–rings should be replaced11 Do not apply adhesive cements to gaskets and similar parts12 Make sure that the ends of a snap ring are not aligned with one of the cutouts and are installedin the groove correctly13 If a worn bushing is to be replaced the sub–assembly containing the bushing must also be re-placed14 Check thrust bearings and races for wear or damage Replace if necessary15 Use petroleum jelly to keep parts in place16 When working with FIPG material you must observe the followingUsing a razor blade and a gasket scraper remove all the old packing FIPG material from thegasket surfaceThoroughly clean all components to remove all the loose materialClean both sealing surfaces with a non–residue solventParts must be reassembled within 10 minutes of application Otherwise the packing FIPG ma-terial must be removed and reapplied2004 COROLLA RM1037U135140–2AUTOMATIC TRANSMISSION TRANS –AUTOMATIC TRANSAXLE FLUID ATMAUTOMATIC TRANSAXLE FLUID ATM400LG–01ON–VEHICLE
