INSPECTION
Installation and Inspection of Torque Converter

After inserting a torque converter to a A/T, be sure to check dis-
tance “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 A/T assembly to the engine assembly, attach the fixing bolts in accordance with the follow-
ing standard.
For VQ35DE models
For VK45DE models
*1 : No.2 bolt also secures A/T fluid charging pipe and washer.
*2 : No.4 bolt also secures bracket.
(A) : A/T to engine

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 9 ,
"COMPONENTS (FOR VQ35DE)" or AT- 2 7 0 , "COMPONENTS
(FOR VK45DE)" .
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" (for VQ35DE) or EM-208, "INSTALLATION" (for
VK45DE)

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-35, "Components (AWD Models)" (for VQ35DE) or
EM-187, "
Components" (for VK45DE).

After completing installation, check A/T fluid leakage, A/T fluid level, and the positions of A/T. Refer to AT-
13, "Checking A/T Fluid" , AT- 2 3 1 , "Checking of A/T Position" .
