A/T FLUID TEMPERATURE SENSOR 2 REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery cable from the negative terminal.
2. Drain ATF through drain plug.
3. Disconnect heated oxygen sensor 2 harness connector.
4. Remove oil pan, oil pan gasket and clips (VQ35DE models) or oil pan, oil pan gasket, brackets and clips
(VK45DE models) according to the following procedures.
a. VQ35DE models
i. Remove clips (1).
ii. Remove oil pan (2) and oil pan gasket.
: Front
: Bolt (22)
b. VK45DE models
i. Remove clips (1) and brackets (2).
ii. Remove oil pan (3) and oil pan gasket.
: Front
: Bolt (22)
5. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
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 4 , "
A/T Fluid Cooler Cleaning" .
6. Disconnect A/T fluid temperature sensor 2 connector.
CAUTION:
Be careful not to damage connector.
