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.
• 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. Refer to TM-186, "
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 sure that transmission rotates
freely without binding.
• Install crankshaft pos ition sensor (POS).
• After completing installation check fluid leakage, fluid level and the
positions of A/T. Refer to TM-148, "
Checking the A/T Fluid (ATF)", TM-164, "Checking of A/T Position" and
