CAUTION: Apply [1][2]ATF to oil pump bearing.





4. Apply recommended sealant (Genuine RTV Silicone Sealant or equivalent.) to oil pump assembly as shown in the figure.

CAUTION: Completely remove all moisture, oil and old sealant, etc. from the oil pump mounting bolts and oil pump mounting bolt mounting surfaces.





5. Tighten oil pump bolts to the specified torque. Refer to AT-254, "Component". Component

CAUTION: Apply [1][2]ATF to oil pump bushing.





6. Install O-ring to input clutch assembly.

CAUTION:
^ Do not reuse O-ring.
^ Apply [1][2]ATF to O-ring.





7. Install converter housing to transmission case. Tighten converter housing bolts (1) to the specified torque. Refer to AT-254, "Component". Component
<---: Bolt

CAUTION: Do not reuse self-sealing bolt (2).





8. Make sure that brake band does not close turbine revolution sensor hole.
9. Install control valve with TCM.





a. Connect TCM connector and park/neutral position switch connector.





b. Install A/T assembly harness connector to control valve with TCM.





c. Connect TCM connectors.





d. Install O-ring to A/T assembly harness connector.

CAUTION:
^ Do not reuse O-ring.
^ Apply [1][2]ATF to O-ring.





e. Install A/T fluid temperature sensor 2 to bracket.





f. Install A/T fluid temperature sensor 2 (with bracket) in control valve with TCM. Tighten A/T fluid temperature sensor 2 bolt to the specified torque. Refer to AT-254, "Component". Component

CAUTION: Adjust bolt hole of bracket to bolt hole of control valve.





g. Install control valve with TCM in transmission case.

CAUTION:
^ Make sure that turbine revolution sensor securely installs turbine revolution sensor hole.
^ Hang down revolution sensor harness toward outside so as not to disturb installation of control valve with TCM.
^ Adjust A/T assembly harness connector of control valve with TCM to terminal hole of transmission case.





^ Assemble it so that manual valve cutout is engaged with manual plate projection.








h. Install bolts A, B and C to control valve with TCM. Tighten bolt 1, 2 and 3 temporarily to prevent dislocation. After that tighten them in order (1 ---> 2 ---> 3), and then tighten other bolts. Tighten control valve bolts to the TCM with specified torque.





10. Connect A/T fluid temperature sensor 2 connector (A).
11. Securely fasten terminal cord assembly and A/T fluid temperature sensor 2 harness with terminal clips (<---).





12. Connect revolution sensor connector.





13. Securely fasten revolution sensor harness with terminal clip.





14. Pull down A/T assembly harness connector.

CAUTION: Be careful not to damage connector.





15. Install snap ring to A/T assembly harness connector.





16. Install magnets in oil pan.
17. Install oil pan, oil pan gasket and clips (VQ35DE models) or oil pan, oil pan gasket, brackets and clips (VK45DE models) according to the following procedures.
a. VQ35DE models
i. Install oil pan gasket to transmission case.

CAUTION:
^ Do not reuse oil pan gasket.
^ Install it in the direction to align hole positions.
^ Complete remove all moisture, oil and old gasket, etc. from oil pan gasket mounting surface.





ii. Install oil pan (2) and clips (1) to transmission case.
<---: Front
<---: Oil pan mounting bolt

CAUTION:
^ Install it so that drain plug comes to the position as shown in the figure.
^ Be careful not to pinch harnesses.
^ Completely remove all moisture, oil and old gasket, etc. from oil pan mounting surface.





iii. Tighten oil pan mounting bolts to the specified torque in numerical order shown in the figure after temporarily tightening them. Tighten oil pan mounting bolts to the specified torque. Refer to AT-254, "Component". Component

CAUTION: Do not reuse oil pan mounting bolts.

b. VK45DE models
i. Install oil pan gasket to transmission case.

CAUTION:
^ Do not reuse oil pan gasket.
^ Install it in the direction to align hole positions.
^ Complete remove all moisture, oil and old gasket, etc. from oil pan gasket mounting surface.





ii. Install oil pan (3), clips (1) and brackets (2) to transmission case.
<---: Front
<---: Oil pan mounting bolt

CAUTION:
^ Install it so that drain plug comes to the position as shown in the figure.
^ Be careful not to pinch harnesses.
^ Completely remove all moisture, oil and old gasket, etc. from oil pan mounting surface.
^ Be careful with installation direction of brackets.





iii. Tighten oil pan mounting bolts to the specified torque in numerical order shown in the figure after temporarily tightening them. Tighten oil pan mounting bolts to the specified torque. Refer to AT-254, "Component". Component

CAUTION: Do not reuse oil pan mounting bolts.

18. Install drain plug to oil pan. Tighten drain plug to the specified torque. Refer to AT-254, "Component". Component

CAUTION: Do not reuse drain plug gasket.

19. Install torque converter.





a. Pour [1][2]ATF into torque converter.
^ Approximately 2 liter (2 - 1/8 US qt, 1 - 3/4 Imp qt) of [1][2]ATF is required for a new torque converter.
^ When reusing old torque converter, add the same amount of [1][2]ATF as was drained.





b. Install torque converter while aligning notches of torque converter with notches of oil pump.

CAUTION: Install torque converter while rotating it.





c. Measure distance "A" to make sure that torque converter is in proper position.
Distance "A"
