Checking A/T Fluid

INFOID:0000000001728293

1.

Warm up engine.

2.

Check for A/T fluid leakage.

3.

Before driving, A/T fluid level can be checked at A/T fluid tem-
peratures of 30 to 50

°

C (86 to 122

°

F) using the “COLD” range

on A/T fluid level gauge.

a.

Park vehicle on level surface and set parking brake.

b.

Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.

c.

Check A/T fluid level with engine idling.

d.

Remove A/T fluid level gauge and wipe clean with lint-free cloth.

CAUTION:

When wiping the A/T fluid level gauge, always use lint-free
cloth.

e.

Re-insert A/T fluid level gauge into A/T fluid charging pipe as far
as it will go.

CAUTION:

Firmly secure the A/T fluid level gauge to the A/T fluid
charging pipe using the stopper attached.

f.

Remove A/T fluid level gauge and note reading. If reading is at
low side of range, add A/T fluid to the A/T fluid charging pipe.

CAUTION:

Do not overfill.

4.

Drive vehicle for approximately 5 minutes.

5.

Re-check A/T fluid level at A/T fluid temperatures of 50 to 80

°

C (122 to 176

°

F) using “HOT” range on A/T

fluid level gauge.

CAUTION:

• When wiping the A/T fluid level gauge, always use lint-free cloth.
• Firmly secure the A/T fluid level gauge to the A/T fluid charging pipe using the stopper attached.

6.

Check A/T fluid condition and make any necessary repairs. If the A/T fluid smells burnt, contains frictional
material (clutches, bands, etc.), or if the A/T is repaired, overhauled, or replaced, inspect and clean the A/
T fluid cooler mounted in the radiator. Refer to 

TM-172, "A/T Fluid Cooler Cleaning"

.

7.

Install the removed A/T fluid level gauge into the A/T fluid charging pipe.

CAUTION:

Firmly secure the A/T fluid level gauge to the A/T fluid charging pipe using the stopper attached.

Changing A/T Fluid

INFOID:0000000001728294

1.

Warm up A/T fluid.

2.

Stop engine.

3.

Drain A/T fluid by removing the drain plug from the transaxle.

4.

Reinstall the drain plug and new gasket and tighten to the specified torque.

A/T FLUID

5.

Refill the transaxle with new specified A/T fluid through the A/T fluid charging pipe. Always refill the tran-
saxle with the same volume of A/T fluid that was drained out.

6.

Run engine at idle speed for 5 minutes.

7.

Check A/T fluid level and condition. Refer to 

TM-171, "Checking A/T Fluid"

.

A/T Fluid Cooler Cleaning

INFOID:0000000001731916

Whenever the A/T is repaired, overhauled, or replaced, the A/T fluid cooler mounted in the radiator must be
inspected and cleaned.
Metal debris and friction material, if present, can become trapped in the A/T fluid cooler. This debris can con-
taminate the newly serviced A/T or, in severe cases, can block or restrict the flow of A/T fluid. In either case,
malfunction of the newly serviced A/T may result.
Debris, if present, may build up as A/T fluid enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.

A/T FLUID COOLER CLEANING PROCEDURE

1.

Identify the A/T inlet and outlet fluid cooler hoses.

2.

Position an oil pan under the A/T inlet and outlet fluid cooler
hoses.

3.

Disconnect the A/T fluid cooler inlet and outlet rubber hoses
from the steel cooler tubes or bypass valve.
NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.

4.

Allow any A/T fluid that remains in the cooler hoses to drain into
the oil pan.

5.

Insert the extension adapter hose of a can of Transmission
Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.

CAUTION:

• Wear safety glasses and rubber gloves when spraying the

Transmission Cooler Cleaner.

• Spray Transmission Cooler Cleaner only with adequate

ventilation.

• Avoid contact with eyes and skin.
• Do not breath vapors or spray mist.

6.

Hold the hose and can as high as possible and spray Transmis-
sion Cooler Cleaner in a continuous stream into the cooler outlet
hose until A/T fluid flows out of the cooler inlet hose for 5 seconds. 

7.

Insert the tip of an air gun into the end of the cooler outlet hose.

8.

Wrap a shop rag around the air gun tip and end of cooler outlet
hose.

9.

Blow compressed air regulated to 5 - 9 kg/cm

2

 (70 - 130 psi) through the cooler outlet hose for 10 seconds

to force out any remaining A/T fluid.

10. Repeat steps 5 through 9 three additional times.

Fluid grade and capacity:

Refer to 

MA-19, "Fluids and Lubricants"

11. Position an oil pan under the banjo bolts that connect the A/T fluid cooler steel lines to the A/T.

12. Remove the banjo bolts.
13. Flush each steel line from the cooler side back toward the A/T by spraying Transmission Cooler Cleaner

in a continuous stream for 5 seconds. 

14. Blow compressed air regulated to 5 - 9 kg/cm

2

 (70 - 130 psi) through each steel line from the cooler side

back toward the A/T for 10 seconds to force out any remaining A/T fluid.

15. Ensure all debris is removed from the steel cooler lines.
16. Ensure all debris is removed from the banjo bolts and fittings.

17. Perform "A/T FLUID COOLER DIAGNOSIS PROCEDURE".

A/T FLUID COOLER DIAGNOSIS PROCEDURE

NOTE:
Insufficient cleaning of the cooler inlet hose exterior may lead to inaccurate debris identification.

1.

Position an oil pan under the A/T inlet and outlet cooler hoses.

2.

Clean the exterior and tip of the cooler inlet hose.

3.

Insert the extension adapter hose of a can of Transmission
Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.

CAUTION:

• Wear safety glasses and rubber gloves when spraying the

Transmission Cooler Cleaner.

• Spray Transmission Cooler Cleaner only with adequate

ventilation.

• Avoid contact with eyes and skin.
• Do not breath vapors or spray mist.

4.

Hold the hose and can as high as possible and spray Transmis-
sion Cooler Cleaner in a continuous stream into the cooler outlet
hose until A/T fluid flows out of the cooler inlet hose for 5 seconds.

5.

Tie a common white, basket-type coffee filter to the end of the
cooler inlet hose.

6.

Insert the tip of an air gun into the end of the cooler outlet hose.

7.

Wrap a shop rag around the air gun tip and end of cooler outlet
hose.

8.

Blow compressed air regulated to 5 - 9 kg/cm

2

 (70 - 130 psi)

through the cooler outlet hose to force any remaining A/T fluid
into the coffee filter.

9.

Remove the coffee filter from the end of the cooler inlet hose.

10. Perform "A/T FLUID COOLER INSPECTION PROCEDURE".

A/T FLUID

1.

Inspect the coffee filter for debris.

a.

If small metal debris less than 1mm (0.040 in) in size or metal
powder is found in the coffee filter, this is normal. If normal
debris is found, the A/T fluid cooler/radiator can be re-used and
the procedure is ended.

b.

If one or more pieces of debris are found that are over 1mm
(0.040 in) in size and/or peeled clutch facing material is found in
the coffee filter, the A/T fluid cooler is not serviceable. The A/T
fluid cooler/radiator must be replaced and the inspection proce-
dure is ended. Refer to 

CO-16, "Removal and Installation"

.

A/T FLUID COOLER FINAL INSPECTION

After performing all procedures, ensure that all remaining oil is cleaned from all components.
