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" .

28. Remove oil pan and oil pan gasket.
29. Check foreign materials in oil pan to help determine causes of malfunction. If the A/T fluid is very dark, smells burned, or con-
tains foreign particles, the frictional material (clutches, band)
may need replacement. A tacky film that will not wipe clean indi-
cates varnish build up. Varnish can cause valves, servo, and
clutches to stick and can inhibit pump pressure.

If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT- 1 5 , "
A/T Fluid Cooler Cleaning" .
30. Remove magnets from oil pan.
31. Disconnect A/T fluid temperature sensor 2 connector. CAUTION:
Be careful not to damage connector.
32. Straighten terminal clips to free terminal cord assembly and A/T fluid temperature sensor 2 harness.
