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 the reference value limit.
INSTALLATION
Install the removed parts in the reverse order of the removal, while paying attention to the following work.

When installing transmission assembly to the engine assembly, attach the fixing bolts in accordance with
the following standard.
For VQ35DE models
For VK45DE models
*: No.2 bolt also secures A/T fluid charging pipe.

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 7 3 ,
"COMPONENTS (FOR VQ35DE)" or AT- 2 7 4 , "COMPONENTS
(FOR VK45DE)" .
CAUTION:

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.

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 Model)" , EM-
185, "Removal and Installation" .

After completing installation, check A/T fluid leakage, A/T fluid level, and the positions of A/T. Refer to AT-
12, "Changing A/T Fluid" , AT- 2 3 5 , "Adjustment of A/T Position" , AT- 2 3 5 , "Checking of A/T Position" .
