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"
