Checking of CVT PositionBCS001MO
1. Place selector lever in “P” position, and turn ignition switch ON. (Do not start engine.)
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transaxle body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. Confirm the back-up lamps illuminate only when lever is placed
in the “R” position. Confirm the back-up lamps do not illuminate
when the selector lever is pushed toward the “R” position side
with the gear position remained in the “P” or “N” position.
7. Confirm the engine can only be started with the selector lever in
the “P” and “N” positions.
8. Make sure transaxle is locked completely in “P” position.
9. When selector lever is set to manual shift gate, make sure man-
ual mode is displayed on combination meter.
Shift selector lever to “+” and “-” sides, and make sure set shift position changes.

INSTALLATION
Note the following, and install in the reverse order of removal.

After completing installation, check for engine coolant leakage, engine coolant level, and the positions of
CVT. Refer to CO-34, "
Inspection" and CVT-179, "Checking of CVT Position" .
CAUTION:

Install hose clamp with tabs aligned with markings of CVT fluid cooler valve assembly and each
hose.

Do not reuse CVT fluid cooler inlet tube assembly and CVT fluid cooler outlet tube assembly.

Apply LLC around O-ring when installing CVT fluid cooler inlet tube and CVT fluid cooler outlet
tube assembly to CVT fluid cooler valve assembly.
COMPONENT INSPECTION
1. Make sure that CVT fluid cooler valve is fully opened at room
temperature.
2. Put CVT fluid cooler valve into a water-filled container, and then
heat it up to 82°C (180°F) or more for 10 minutes or more.
3. Make sure that CVT fluid cooler valve is fully closed.Standard

Install transaxle assembly to engine assembly with a hoist.

When installing fluid cooler tube to transaxle assembly, assem-
ble the part with the tube aligned with the rib.

When installing transaxle to the engine, attach the fixing bolts in
accordance with the following standard.

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

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

When tightening the tightening nuts for the torque con-
verter after fixing the crankshaft pulley bolts, be sure to
confirm the tightening torque of the crankshaft pulley
mounting bolts. Refer to EM-181, "
INSTALLATION" .

After converter is installed to drive plate, rotate crankshaft several turns and check to be sure
that transaxle rotates freely without binding.

Install crankshaft position sensor (POS). Refer to EM-145, "Removal and Installation" .

After completing installation, check for fluid leakage, fluid level, and the positions of CVT. Refer to CVT-13,
