A method of rebuilding a solenoid for use in automatic transmissions is disclosed. In one embodiment, an improvement over the original equipment design allows for increased durability of the solenoid. In another embodiment, a lower cost method is disclosed for reusing an expensive component. In either case, various components within the solenoid are reused, reconditioned or replaced. A preferred process for disassembling the solenoid is also disclosed.

1. A method for restoring a used solenoid and valve assembly from an automatic transmission, comprising: providing a new bushing, and a used solenoid assembly including a solenoid housing connected to a valve housing, the solenoid housing holding within it an electromagnetic actuator supported by a used bushing and biased along a direction of an axial position of a set screw that supports the used bushing, the valve housing holding within it a spool valve movable by the actuator along an axis of the direction;removing the used bushing from the set screw;installing a new bushing in the set screw after said removing;testing hydraulic characteristics of the used solenoid assembly with the new bushing; andbiasing the actuator along the direction by turning the set screw. 2. The method of claim 1 wherein the new bushing comprises bronze material. 3. The method of claim 1 wherein the new bushing is lubricated with graphite. 4. The method of claim 1 which further includes locking the position of the set screw before said testing. 5. The method of claim 1 wherein the biasing occurs after the installing. 6. The method of claim 1 wherein the new bushing comprises one of polytetrafluoroethylene, nylon, a self-lubricating alloy, and a composite material. 7. The method of claim 1 wherein the new bushing comprises a multiple piece type bushing. 8. The method of claim 1 wherein the new bushing is coated with an adhesive before the installing. 9. The method of claim 1 wherein the new bushing comprises a self-lubricating graphite/bronze material, and the used bushing does not comprise a self-lubricating graphite/bronze material. 10. A method for restoring a used solenoid and valve assembly from an automatic transmission, comprising: providing a new bushing, and a used solenoid assembly including a solenoid housing connected to a valve housing, the solenoid housing holding within it an electromagnetic actuator supported by a used bushing and biased along a direction of an axial position of a set screw that supports the used bushing, the valve housing holding within it a spool valve movable by the actuator along an axis of the direction;removing the used bushing;installing a new bushing in direct contact with the set screw after said removing;testing hydraulic characteristics of the used solenoid assembly with the new bushing; andbiasing the actuator along the direction by turning the set screw. 11. The method of claim 10 wherein the new bushing comprises bronze material. 12. The method of claim 10 wherein the new bushing is lubricated with graphite. 13. The method of claim 10 which further includes locking the position of the set screw before said testing. 14. The method of claim 10 wherein the biasing occurs after the installing. 15. The method of claim 10 wherein the new bushing comprises a steel bushing coated with one of polytetrafluoroethylene, nylon, bronze, a self-lubricating alloy, and a composite material. 16. The method of claim 10 wherein the new bushing comprises one of polytetrafluoroethylene, nylon, a self-lubricating alloy, and a composite material. 17. The method of claim 10 wherein the new bushing comprises a multiple piece type bushing. 18. The method of claim 10 wherein the new bushing is coated with an adhesive before the installing. 19. The method of claim 10 wherein the new bushing comprises a self-lubricating graphite/bronze material, and the used bushing does not comprise a self-lubricating graphite/bronze material. 20. The method of claim 1, wherein the set screw is a used set screw.
