• When replacing an engine or transmission you must make sure any dowels are installed correctly during re-assembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.
• Do not reuse O-rings and copper washers. Refer to "COMPONENTS".
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the bolts for th e torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-156
.
• After converter is installed to drive plate, ro tate crankshaft several turns to check that transaxle
rotates freely without binding.
• When installing the torque converter to the transaxle measure dis- tance A.
• Check the fitting of the dowel pins when installing the transaxle assembly and the engine assembly.

11. Remove oil pan bolts.
12. Remove oil pan and oil pan gasket.
13. 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. Refer to CO-40
.
14. Remove magnets from oil pan.

INTELLIGENT KEY SYSTEM
System Description
INFOID:0000000005396599
• The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function), and start the engine (engine start func tion) by carrying around the Intelligent Key (without
some key operation), which operates based on the results of electronic ID verification using two-way com-
munications between the Intelligent Key and the vehicle (Intelligent Key unit).
• Vehicles equipped with a manual transmission include a key interlock solenoid located in the steering col- umn to prevent accidental shut-off of the ignition sw itch and locking of the steering wheel during driving con-
dition when the vehicle is moving.
CAUTION:
The driver should always carry the Intelligent Key
• Operation of the remote controller buttons on the Inte lligent Key also provides the same functions as the
remote control entry system. (Remote keyless entry functions)
• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer
goes off to inform the driver. (Warning chime functions)
• When a door lock is locked or unlocked with request switch or remote controller button operation, the hazard
lamps flash and the buzzer (outside vehicle) sounds (Hazard and buzzer reminder function).
• Even if the Intelligent Key battery is completely discharged, the door locks can be locked and unlocked and the engine started with the mechanical key built into the Intelligent Key.
• The settings for each function can be changed with the CONSULT-III.
• If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be registered.
• It has been made possible to diagnose the system and r egister an Intelligent Key with the CONSULT-III.
DOOR LOCK/UNLOCK FUNCTION
Only when pressing the request switch, it is possible to lock and unlock the door by carrying around the Intelli-
gent Key (without some key operation).
