INSTALLATION
Install the removed parts in the reverse order of the removal, while paying attention to the following work.
 When installing A/T assembly to the engine assembly, attach the fixing bolts in accordance with the following standard.
 Align the positions of tightening bo lts for drive plate with those of
the torque converter, and temporarily tighten the bolts. Then,
tighten the bolts with the specified torque. Refer to "COMPO-
NENTS".
CAUTION:
 Do not reuse O-ring and copper washers.
 When turning crankshaft, turn it clockwise as viewed from the
front of the engine.
 When tightening the tightening bolts for the torque converter
after fixing the crankshaft pulley bolts, be sure to confirm the
tightening torque of the cr ankshaft pulley mounting bolts.
Refer to EM-65, "
Removal and Installation".
 After converter is installed to drive plate, rota te crankshaft several turns and check to be sure that
transmission rotates freely without binding.
 Install crankshaft position sensor (POS). Refer to EM-30, "
Removal and Installation (2WD Models)".
 After completing installation, check A/T fluid leakage, A/T fluid level, and the A/T positions of A/T. Refer to
AT- 11 , "
Checking A/T Fluid", AT-207, "Checking of A/T Position".
