the specified torque. Refer to DLN-142, "
Disassembly and
Assembly".
CAUTION:
Do not reuse gasket.
FILLING
1. Remove the filler plug and gasket.
2. Fill the transfer with new fluid until the fluid level reaches the specified limit near the filler plug hole.
CAUTION:
Carefully fill fluid. (Fil l up for approx. 3 minutes.)
3. Leave the vehicle for 3 minutes, and check fluid level again.
4. Install the filler plug with a new gasket to the transfer. Tighten to the specified torque. Refer to DLN-142, "
Disassembly and
Assembly".
CAUTION:
Do not reuse gasket.
Checking Propeller ShaftINFOID:0000000003777001
Check the front and rear propeller shafts for damage, dents, and cracks. Check the joints for looseness and
any damage. Repair or replace as necessary.
Checking Front Final Drive OilINFOID:0000000004215541
DIFFERENTIAL GEAR OIL LEAKAGE AND LEVEL
1. Make sure that differential gear oil is not leaki ng from the front final drive assembly or around it.
2. Check the differential gear oil level from the filler plug hole as shown.
CAUTION:
Do not start engine while checki ng differential gear oil level.
3. Install the filler plug with sealant applied on the threads to the front final drive assembly. Tighten to the specified torque. Refer
to DLN-217, "
Disassembly and Assembly".
• Use High Performance Thread Sealant or equivalent. Refer to GI-15, "
Recommended Chemical Products and Sealants".

A/T FLUID
Checking the A/T Fluid (ATF)INFOID:0000000004187473
CAUTION:
If using the vehicle for towing, the A/T fl uid must be replaced as specified. Refer to MA-8, "Introduc-
tion of Periodic Maintenance".
1. Before driving, the A/T fluid level can be checked at A/T fluid temperatures of 30 ° to 50 ° C (86 ° to 122 ° F) using the “COLD”
range on the A/T fluid level gauge as follows:
a. Park the vehicle on a level surface and set the parking brake.
b. Start the engine and move the selector lever through each gear position. Shift the selector lever into the “P” position.
c. Check the A/T fluid level with the engine idling.
d. Remove the A/T fluid level gauge and wipe it clean with a lint- free paper.
CAUTION:
When wiping the A/T fluid fr om the A/T fluid level gauge,
always use a lint-free paper, not a cloth.
e. Re-insert the A/T fluid level gauge into the A/T fluid charging pipe until the cap contacts the t op of the A/T fluid charging pipe
as shown.
CAUTION:
To check A/T fluid level, insert th e A/T fluid level gauge until
the cap contacts the top of the A/T fluid charging pipe, with
the gauge reversed from the normal inserted position.
f. Remove the A/T fluid level gauge and note the A/T fluid level. If the A/T fluid level is at low side of range, add A/T fluid to the
transmission through the A/T fluid charging pipe.
CAUTION:
Do not overfill the tran smission with A/T fluid.
g. Install the A/T fluid level gauge and the A/T fluid level gauge bolt.
2. Warm up the engine and transmission.
3. Check for any A/T fluid leaks.
4. Drive the vehicle to increase the A/T fluid temperature to 80 ° C (176 ° F).

Changing the A/T Fluid (ATF)INFOID:0000000005892327
CAUTION:
If using the vehicle for towing, the A/T fl uid must be replaced as specified. Refer to MA-8, "Introduc-
tion of Periodic Maintenance".
1. Drive the vehicle to warm up the A/T fluid to approximately 80 ° C (176 ° F).
2. Stop the engine.
3. Remove the A/T fluid level gauge.
4. Drain the A/T fluid from the drai n plug hole, then install the drain
plug with a new gasket. Refill the transmission with new A/T
fluid. Always refill with the same volume as the drained A/T fluid.
Use the A/T fluid level gauge to check the A/T fluid level as
shown. Add A/T fluid as necessary.
 To flush out the old A/T fluid from the transmission o il coolers, pour new A/T fluid into the A/T fluid charg-
ing pipe with the engine idling and at the same time drain the old A/T fluid from the auxiliary transmis-
sion oil cooler hose return line.
 When the color of the A/T fluid coming out of the aux iliary transmission oil cooler hose return line is
about the same as the color of the new A/T fluid, flushing out the old A/T fluid is complete. The amount
of new A/T fluid used for flushing should be 30% to 50% increase of the specified capacity.
CAUTION:
 If Genuine NISSAN Matic S ATF is not available, Genuine NISSAN Matic J ATF may also be used.
 Using ATF fluid other than Genuine NISSAN Matic S ATF or Matic J ATF will cause deterioration
in driveability and A/T durability, and may damage the A/T, which is not covered by the warranty.
 When filling the transmission with A/T fluid, do not spill the A/T fluid on any heat generating
parts such as the exhaust parts.
 Do not reuse the drain plug gasket.
5. Install the A/T fluid level gauge and tighten t he A/T fluid level gauge bolt to specification.
6. Drive the vehicle to warm up the A/T fluid to approximately 80 ° C (176 ° F).
7. Check the fluid level and condition. If the A/T fluid is still dirty, repeat steps 2 through 6.
8. Install the A/T fluid level gauge in the A/T fluid charging pipe and install the A/T fluid level gauge bolt.
9. Tighten the A/T fluid level gauge bolt to specification. Drain plug : Refer to
TM-201, "Oil Pan"
