REMOVAL AND INSTALLATION
Removal
1. Remove rear propeller shaft. Refer to PR-8, "Removal and
Installation" .
2. Remove transfer assembly from A/T assembly (AWD models).
Refer to TF-44, "
Removal and Installation" .
3. Remove rear oil seal using a flat-bladed screwdriver.
CAUTION:
Be careful not to scratch rear extension assembly (2WD

CAUTION:
After completing installation, check for A/T fluid leakage and A/T fluid level. Refer to AT- 1 3 , "
Checking
A/T Fluid" .
1. As shown in the figure, use the drift to drive rear oil seal into rear
extension assembly (2WD models) or adapter case assembly
(AWD models) until it is flush.

7. 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" .
8. Support A/T assembly with a transmission jack.
CAUTION:
When setting transmission jack, place wooden blocks to
prevent from damaging control valve with TCM and trans-
mission case.
9. Remove rear engine mounting member with power tool. Refer to AT-271, "
Removal and Installation (2WD
Models)" .
10. Remove rear extension assembly (VQ35DE models) or output shaft & companion flange complement
(VK45DE models) according to the following procedures.
a.VQ35DE models
i. Remove tightening bolts for rear extension assembly and trans-
mission case.
ii. Tap rear extension assembly with a soft hammer.
iii. Remove rear extension assembly from transmission case. (With
needle bearing.)

28. Remove oil pan and oil pan gasket.
29. 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

If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT- 1 4 , "

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.

vii. Remove parking gear from output shaft.
viii. Remove seal rings from output shaft.
44. Remove needle bearing from transmission case.
45. Remove revolution sensor from transmission case.
CAUTION:
Do not subject it to impact by dropping or hitting it.
Do not disassemble.
Do not allow metal filings, etc., to get on the sensor's
front edge magnetic area.
Do not place in an area affected by magnetism.
46. Remove reverse brake snap ring (fixing plate) using 2 flat-
bladed screwdrivers.
NOTE:
Press out snap ring from the transmission case oil pan side gap
using a flat-bladed screwdriver, and remove it using a another
screwdriver.
47. Remove reverse brake retaining plate from transmission case.
Check facing for burns, cracks or damage. If necessary,
replace the plate.

After compressor service operation, turn the compressor shaft by hand more than five turns in
both directions. This will equally distribute lubricant inside the compressor. After the compressor
is installed, let the engine idle and operate the compressor for one hour.
After replacing the compressor magnet clutch, apply voltage to the new one and check for normal
operation.
Precautions for Service EquipmentNJS000FU
RECOVERY/RECYCLING EQUIPMENT
Be certain to follow the manufacturer’s instructions for machine operation and machine maintenance. Never
introduce any refrigerant other than that specified into the machine.
ELECTRICAL LEAK DETECTOR
Be certain to follow the manufacturer’s instructions for tester operation and tester maintenance.
VACUUM PUMP
The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric pres-
sure. So the vacuum pump lubricant may migrate out of the pump
into the service hose. This is possible when the pump is switched off
after evacuation (vacuuming) and hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as follows.
Usually vacuum pumps have a manual isolator valve as part of
the pump. Close this valve to isolate the service hose from the
pump.
For pumps without an isolator, use a hose equipped with a man-
ual shut-off valve near the pump end. Close the valve to isolate
the hose from the pump.
If the hose has an automatic shut-off valve, disconnect the hose
from the pump. As long as the hose is connected, the valve is
open and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under no vacuum condition. Such valves may restrict the pump’s
ability to pull a deep vacuum and are not recommended.
MANIFOLD GAUGE SET
Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2
-16 ACME threaded connections for ser-
vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified lubricants.
