b. Install oil pan gasket on transaxle case.
CAUTION:
• Completely remove all moisture, oil and old gasket, etc.
from the oil pan gasket mounting surface of transaxle
case.
• Do not reuse oil pan gasket.
c. Install oil pan on transaxle case.
CAUTION:
Completely remove all moisture, oil and old gasket, etc.
from the oil pan gasket mounting surface of oil pan.
d. Tighten oil pan fitting bolts (1) to the specified torque. Refer to
AT-230, "
Component".
CAUTION:
• Always replace oil pan fitting bolts (1) as they are self-sealing bolts.
• Tighten four bolts in a criss-cross pattern to prevent dislocation of gasket.
e. Install drain plug gasket and drain plug (2) to oil pan.
CAUTION:
Do not reuse drain plug gasket.
f. Tighten drain plug to the specified torque. Refer to AT-230, "
Component".
29. Install PNP switch (2) on transaxle case.
: Bolt (3)
a. Set manual shaft (1) in “P” position.
b. Temporarily install PNP switch (2) on manual shaft (1).
c. Set manual shaft (1) in “N” position.
d. Use a 4 mm (0.16 in) dia. pin for this adjustment.
i. Insert the pin straight into the manual shaft (1) adjustment hole.
ii. Rotate PNP switch (2) until the pin can also be inserted straight
into hole in PNP switch (2).
e. Tighten PNP switch fitting bolts to the specified torque. Refer to
AT-230, "
Component".
f. Remove pin from adjustment hole after adjusting PNP switch (2).
30. Install O-ring (3) to turbine revolution sensor (power train revolu-
tion sensor) (1).
31. Install turbine revolution sensor (power train revolution sensor)
(1) to transaxle case (2).
: Bolt (1)
32. Tighten turbine revolution sensor (power train revolution sensor)
fitting bolt to the specified torque. Refer to AT-230, "
Compo-
nent".
33. Install revolution sensor (1) to transaxle case (2).
34. Tighten revolution sensor fitting bolts to the specified torque.
Refer to AT-230, "

35. Install torque converter.
a. Pour ATF into torque converter.
•Approximately 1 liter (1 US qt, 7/8 Imp pt) of fluid is
required for a new torque converter.
•When reusing old torque converter, add the same amount
of ATF as was drained.
b. Install torque converter while aligning notches of torque con-
verter with notches of oil pump.
c. Measure distance “A” to make sure that torque converter is in
proper position.
