INSPECTION
Installation and Inspection of Torque Converter

●

After inserting the torque converter to the transmission, check
dimension "A" to ensure it is within the reference value limit.

INSTALLATION

Installation is in the reverse order of the removal.

●

When installing transmission to the engine, tighten the bolts to
the specified torque using sequence 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 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 

MA-22, "Checking the Automatic Transmission Fluid (ATF)"

 , 

AT-222,

"Checking of A/T Position"

  and
