INSPECTION
Installation and Inspection of Torque Converter
 After inserting a torque converter to a transmission, be sure to check distance A to ensure it is within specifications.
INSTALLATION
Installation of the remaining components is in the revers e order of removal, while paying attention to the fol-
lowing:
 When installing transmission to the engine, attach the bolts as shown.
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 components.
NOTE:
*: No.2 bolt also secures air breather vent.
 Align the positions of bolts for dr ive plate with those of the torque
converter, and temporarily tighten the bolts. Then tighten the bolts
with the specified torque. Refer to TM-216, "Removal and Installa-
tion (4WD)".
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 TM-179, "Checking the A/T Fluid (ATF)"
, TM-195, "Checking of A/T Position"
and TM-195, "Adjustment of A/T Position".
Distance A : 24.0 mm (0.94 in) or more
