g. Install control valve with TCM in transmission case.CAUTION:
 Make sure that turbine revolu tion sensor securely installs
turbine revolution sensor hole.
 Hang down revolution senso r harness toward outside so
as not to disturb installation of control valve with TCM.
 Adjust A/T assembly harness co nnector 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.  : Front
i. Tighten bolt 1, 2 and 3 temporarily to prevent dislocation. After that tighten them in order (1 → 2 → 3), and then tighten other
bolts to the specified torque. Refer to AT-249, "

16. Install magnets in oil pan.
17. Install oil pan to transmission case.
a. 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.
b. Install oil pan (3) (with oil pan gasket), clips (2) and brackets (1) (VK45DE) to transmission case.
 : Vehicle front
 : Bolt (22)
CAUTION:
 Install it so that drain plug (4) 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 gasket mounting surface.
c. Tighten oil pan mounting bolts to the specified torque in numeri- cal order shown in the figure after temporarily tightening them.
Refer to AT-249, "
Component".
CAUTION:
Do not reuse oil pan mounting bolts.
18. Install drain plug to oil pan, and then tighten drain plug mounting bolts to the specified torque. Refer to AT-249, "
Component".
CAUTION:
Do not reuse drain plug gasket.
19. Install torque converter.
a. Pour ATF into torque converter. Approximately 2 liter (2-1/8 US qt, 1-3/4 Imp qt) of ATF is
required for a new torque converter.
 When reusing old torque converter, add the same amount
of ATF as was drained.
