TRANSMISSION ASSEMBLY
• When installing transmission to the engine, attach the bolts in the order 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.
CAUTION:
• When turning crankshaft, turn it clockwi se as viewed from the front of the engine.
• After converter is installed to drive plate, rota te crankshaft several turns and check to be sure that
transmission rotates fr eely without binding.
NOTE:
• 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.
• Install crankshaft pos ition sensor (POS).
• After completing installation check fluid leakage, fluid level and the positions of A/T. Refer to TM-178, "
Checking the A/T Fluid (ATF)",
TM-194, "
Checking of A/T Position" and TM-194, "Adjustment of A/
T Position".
