AUTOMATIC TRANSMISSION — Component Groups AT-51 COMPONENT GROUP DISASSEMBLY, INSPECTION AND ASSEMBLY The instructions here are organized so that you work on only one component group at a time. This will help avoid confusion of similar-looking parts from different subassemblies being on your workbench at the same time. The component groups are inspected and repaired from the converter housing side. As much as possible, complete the inspection, repair, assembly before proceeding to the next component group. If a component group cannot be assembled because parts are being ordered, be sure to keep all parts of that group in a separate container while proceeding with disassembly, inspection, repair and assembly of other component groups. GENERAL CLEANING 1. All disassembled parts should be washed clean and the fluid passages and holes blown through with compressed air to make sure that they are not clogged. 2. Cleaning solvent used should be the recommended ATF or kerosene. 3. When using compressed air to dry parts, keep face away to avoid spraying solvent in your face. PARTS ARRANGEMENT 1. After cleaning, the parts should be arranged in proper order to allow performing the inspection, and reassembly with efficiency. 2. New brakes and clutches that are to be used for replacement must be soaked in transmission fluid for at least two hours before assembly. 3. When disassembling a valve body, be sure to keep each valve together with the corresponding spring. GENERAL ASSEMBLY 1. All oil seal rings, clutch discs, clutch plates, rotating parts, and sliding surfaces should be coated with transmission fluid prior to reassembly. 2. If a worn bushing is to be replaced, the replacement must be made with the subassembly containing that bushing. 3. All gaskets and rubber O-rings should be replaced. 4. Check thrust bearings and races for wear or damage. Replace if necessary. 5. Make sure that the ends of a snap ring are not aligned with one of the cutouts and are installed in the groove correctly. 6. Use petroleum jelly to keep parts in place.
