INSTALLATION
Installation of the remaining components is in the reverse order of the removal, while paying attention to the
following:
When installing transmission to the engine, attach the bolts as shown.
NOTE:
*: No.2 bolt also secures air breather vent.
CAUTION:
When replacing an engine or transmission you must
make sure the dowels are installed correctly during re-
assembly.
Improper alignment caused by missing dowels may
cause vibration, oil leaks or breakage of drivetrain com-
ponents.
Align the positions of bolts for drive plate with those of the torque
converter, and temporarily tighten the bolts. Then tighten the
bolts with the specified torque.
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 sure 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 AT- 1 2 , "
Checking Automatic Transmission Fluid (ATF)" , AT- 2 2 7 , "Checking
of A/T Position" and AT- 2 2 7 , "Adjustment of A/T Position" .
Transmission to engine bolts : 113 N·m (12 kg-m,
