Valve Body

DISASSEMBLY

NOTE: If the valve body is being reconditioned or replaced, it is necessary to perform the Quick Learn Procedure using the DRB111- Scan Tool
. Remove manual shaft seal.





2. Remove manual shaft screw (Fig. 283).





3. Remove Transmission Range Sensor (TRS) and manual shaft (Fig. 284).





4. Remove Solenoid/Pressure Switch Assembly from valve body (Fig. 285).





5. Remove valve body stiffener plate (Fig. 286).





6. Invert valve body assembly and remove transfer plate-to-valve body screws (Fig. 287).





7. Remove transfer/separator plate from valve body (Fig. 288)





8. Remove separator plate-to-transfer plate screws (Fig. 289).





9. Remove separator plate from transfer plate (Fig. 290).





10. Remove the oil screen from the transfer plate (Fig. 291).





11. Remove thermal valve (Fig. 292) from transfer plate.





12. Remove valve body check balls. Note their location for assembly ease (Fig. 293).





13. Remove 2/4 accumulator assembly as shown in (Fig. 294).





14. Remove dual retainer plate from valve body. Use special tool 6301 to remove plate (Fig. 295).





15. Remove regulator valve spring retainer (Fig. 296).





16. Remove remaining retainers as shown in (Fig. 297).





17. Remove valves and springs as shown in (Fig. 298).
18. 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.

ASSEMBLY

NOTE: If the valve body assembly is being reconditioned or replaced, it is necessary to perform the Quick Learn Procedure using the DRB111- Scan Tool.





1. Install valves and springs as shown in (Fig. 299).





2. Install regulator valve spring retainer (Fig. 300).





3. Install dual retainer plate using Tool 6301 (Fig. 301).





4. Verify that all retainers are installed as shown in (Fig. 302). Retainers should be flush or below valve body surface.





5. Install 2/4 Accumulator components as shown in (Fig. 303). Torque 2/4 Accumulator retainer plate to 5 Nm (45 inch lbs.).





6. Install check balls into position as shown in (Fig. 304). If necessary, secure them with petrolatum or transmission assembly gel for assembly ease.





7. Install thermal valve to the transfer plate (Fig. 305).





8. Install the oil screen to the transfer plate (Fig. 306).





9. Install separator plate to transfer plate (Fig. 307).





10. Install the two separator plate-to-transfer plate screws (Fig. 308).





11. Install the transfer plate to the valve body (Fig. 309).





12. Install the transfer plate-to-valve body screws (Fig. 310) and torque to 5 Nm (45 inch lbs.).





13. Install the stiffener plate (Fig. 311).





14. Install the solenoid/pressure switch assembly and to the transfer plate (Fig. 312) and torque to 5.5 Nm (50 inch lbs.).





15. Install the manual shaft/rooster comb and transmission range sensor to the valve body (Fig. 313).





16. Install the TRS/manual shaft retaining screw (Fig. 314) and torque to 5 Nm (45 inch lbs.).
