• The spiral cable may snap du e to steering operation if the
cable is not installed in the correct position.
• With the steering linkage disconnected, the cable may snap
by turning the steering wheel beyond the limited number of

REMOVAL
1. Set the front wheels in the straight-ahead position.
2. Remove the driver air bag module. Refer to SR-5, "Removal and Installation"
.
3. Disconnect steering wheel switches.
4. Remove the steering wheel center nut.
5. Remove the steering wheel using Tool.
CAUTION:
Place a piece of tape across the sp iral cable so it will not be
rotated out of position.
6. Disconnect heated steering wheel connector.
7. Inspect the steering wheel near the puller holes for damage. If damaged, replace the steering wheel.
 Remove steering wheel rear cover and steering wheelswitches, if required.
INSTALLATION
Installation is in the reverse order of removal.
 Refer to BRC-8, "ADJUSTMENT OF STEERING ANGLE SEN-
SOR NEUTRAL POSITION : Special Repair Requirement" for
steering angle sensor adjustment.
 Align spiral cable correctly when installing steering wheel. Make sure that the spiral cable is in the neutral position. The neutral
position is detected by turning left 2.5 revolutions from the right
end position and ending with the knob at the top.
 After the work is completed, perform self-diagnosis to make sure no malfunction is detected. Refer to SRC-13, "SRS Operation
Check".
 Tighten steering wheel center nut to specification. SR-7, "Removal
and Installation".
CAUTION:
 The spiral cable may snap due to steering operation if the
cable is not installed in the correct position.
 With the steering linkage di sconnected, the cable may snap
by turning the steering wheel beyond the limited number of
turns. The spiral cable can be turned counterclockwise about
2.5 turns from the neutral position. Tool number : ST27180001 (J-25726-A)

TRANSMISSION ASSEMBLY
 When installing transmission to the engine, attach the bolts in theorder as shown.
CAUTION:
 When replacing an engine or transmission you must make
sure the dowels are installe d correctly during re-assembly.
 Improper alignment caused by missing dowels may cause
vibration, oil leaks or breakage of drivetrain components.
NOTE:
*: No.2 bolt also secures air breather vent.
 Align the positions of bolts for drive plate with those of the torque converter, and temporarily tight en the bolts. Then tighten the bolts
with the specified torque. Refer to TM-214, "Removal and Installa-
tion (2WD)".
CAUTION:
 When turning crankshaft, turn it clockwise as viewed from
the front of the engine.
 After converter is installed to drive plate, rotate crankshaft several turns and check to be su re that transmission rotates
freely without binding.
 Install crankshaft position sensor (POS).
 After completing installation check fluid leakage, fluid level and the positions of A/T. Refer to TM-179, "Checking the A/T Fluid (ATF)"
, TM-195, "Checking of A/T Position" and
TM-195, "Adjustment of A/T Position"
