Align the positions of tightening bolts for drive plate with those of
torque converter, and temporarily tighten bolts. Then, tighten
bolts with the specified torque.
CAUTION:

When turning crankshaft, turn it clockwise as viewed from
front of engine.

When tightening the tighten bolts for the torque converter
after fixing crankshaft pulley bolts, be sure to confirm the
tightening torque of crankshaft pulley mounting bolts.
Refer to EM-53, "
TIMING CHAIN" (QR engine), EM-173, "TIMING CHAIN" (VQ engine).

After converter is installed to drive plate, rotate crankshaft several turns and make sure that tran-
saxle rotates freely without binding.

Install POS sensor. Refer to EM-145, "Removal and Installation" .

After completing installation, check for A/T fluid leakage, A/T fluid level, and positions of A/T. Refer to AT-
14, "Checking A/T Fluid" , AT- 2 1 5 , "Adjustment of A/T Position" , AT- 2 1 5 , "Checking of A/T Position" . : 52 N·m (5.3 kg-m, 38 ft-lb)

DISASSEMBLY

5. Set manual shaft to “P” position.
6. Remove PNP switch.
7. Remove bracket from transaxle case.
8. Remove revolution sensor from transaxle case.
9. Remove O-ring from revolution sensor.
10. Remove turbine revolution sensor (power train revolution sen-
sor) from transaxle case.
11. Remove O-ring from turbine revolution sensor (power train revo-
lution sensor).
12. Remove oil pan fitting bolts.
13. Remove oil pan and oil pan gasket.
14. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.

If frictional material is detected, replace radiator after
repair of A/T.
15. Remove magnets from oil pan.
16. Remove control valve assembly according to the following procedures.
a. Remove snap ring from terminal body.
CAUTION:
Do not expand snap ring excessively.
b. Push terminal body into transaxle case and draw out terminal
cord assembly.

ASSEMBLY

CAUTION:

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

Tighten four bolts in a crisscross pattern to prevent dislocation of gasket.
e. Install drain plug gasket on drain plug.
CAUTION:
Do not reuse drain plug gasket.
f. Tighten drain plug to the specified torque. Refer to AT- 2 4 6 , "
Components" .
22. Install PNP switch according to the following procedures.
a. Set manual shaft in “P” position.
b. Temporarily install PNP switch on manual shaft.
c. Move selector lever to “N” position.
d. Use a pin [3 mm (0.12 in) dia.] for this adjustment.
i. Insert the pin straight into the manual shaft adjustment hole.
ii. Rotate PNP switch until the pin can also be inserted straight into
hole in PNP switch.
e. Tighten PNP switch fitting bolts. Refer to AT- 2 4 6 , "
Components"
.
f. Remove pin from adjustment hole after adjusting PNP switch.
