Revision: 2006 December 2006 FX35/FX45
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 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 AT- 2 6 6 ,
"COMPONENTS" .
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 con-
verter after fixing the crankshaft pulley bolts, be sure to
confirm the tightening torque of the crankshaft pulley
mounting bolts. Refer to EM-72, "
INSTALLATION" .

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). 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- 1 3 , "
Checking A/T Fluid" , AT- 2 3 1 , "Checking of A/T Position" .
