Disassembly

DISASSEMBLY

NOTE: If the valve body is being reconditioned or replaced, it is necessary to perform the Quick Learn Procedure using the scan tool.




1. Remove the electrical connectors from the pressure control solenoid (1) and the line pressure sensor (2).
2. Remove the screws (6) holding the pressure control solenoid (1) and line pressure sensor (2) to the valve body.
3. Remove the pressure control solenoid and line pressure sensor from the valve body.
4. Remove the shoulder screw (3) holding the variable line pressure header (4) to the valve body.
5. Remove the variable line pressure header from the manual shaft (5).




6. Remove manual shaft seal.
7. Remove manual shaft screw (1).




8. Remove Transmission Range Sensor (TRS) (1) and manual shaft (2).




9. Remove Solenoid/Pressure Switch Assembly (1) from valve body.




10. Remove valve body stiffener plate (1).




11. Invert valve body assembly and remove transfer plate-to-valve body screws (1).




12. Remove transfer/separator plate (1) from valve body (2).




13. Remove separator plate-to-transfer plate screws (2).




14. Remove separator plate (1) from transfer plate (2).




15. Remove the oil screen (1) from the transfer plate.




16. Remove thermal valve (1) from transfer plate.




17. Remove valve body check balls (1-4). Note their location for assembly ease.




18. Remove 2/4 accumulator assembly (1-5).




19. Remove dual retainer plate (2) from valve body. Use Remover/Installer 6301 (1) to remove plate (2).




20. Remove regulator valve spring retainer (2).




21. Remove remaining retainers (1, 2).




22. Remove all valves and springs.
23. Cleanliness through entire disassembly and assembly of the valve body cannot be overemphasized. When disassembling, each part should be washed in a suitable solvent, then dried by compressed air. Do not wipe parts with shop towels. All mating surfaces in the valve body are accurately machined; therefore, careful handling of all parts must be exercised to avoid nicks or burrs.
