g. Install control valve with TCM in transmission case.
CAUTION:

Make sure that turbine revolution sensor securely installs
into turbine revolution sensor hole.

Adjust A/T assembly harness connector of control valve
with TCM to terminal hole of transmission case.

Hang down revolution sensor harness toward outside so
as not to disturb installation of control valve with TCM.

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.
i. Tighten bolt 1, 2 and 3 temporarily to prevent dislocation. Then tighten them in order (1 → 2 → 3), and then tighten other bolts.
j. Tighten control valve with TCM bolts to the specified torque. Refer to AT- 2 5 0 , "

16. Install the oil pan magnets as shown.
17. Install the oil pan and new oil pan gasket.
CAUTION:

Do not reuse the oil pan gasket.

Completely remove all moisture, oil and old gasket from
the oil pan gasket mating surfaces and holes.

Always replace the oil pan bolts as they are self-sealing.

Be sure the oil pan drain plug hole is located to the rear
of the transmission assembly.

Partially install the oil pan bolts in a criss-cross pattern to
prevent dislocation of the gasket.

Be careful not to pinch harnesses.
18. Tighten new oil pan bolts in numerical order as shown.
19. Install drain plug in oil pan with new gasket. CAUTION:
Do not reuse the drain plug gasket.
20. Install torque converter.
a. Pour ATF into torque converter.

Approximately 2 liter (2-1/8 US qt, 1-3/4 Imp qt) of fluid is
required for a new torque converter.

When reusing old torque converter, add the same amount
of fluid as was drained.
