A/T FLUID
5. Run engine at idle speed for 5 minutes.
6. Check A/T fluid level and condition. Refer to AT-17, "
Checking A/T Fluid".
A/T Fluid Cooler CleaningINFOID:0000000005928072
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 becom e trapped in the A/T fluid cooler. This debris can con-
taminate the newly serviced A/T or, in severe cases, can bloc k 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 c ooler 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 breathe 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 t he 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 (490 - 883 kPa, 71 - 128 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.
11. Position an oil pan under the banjo bolts that connec t the A/T fluid cooler steel lines to the A/T.
12. Remove the banjo bolts. Fluid grade and capacity: Refer to
MA-14

A/T CONTROL SYSTEM
• *1: Operates when OD OFF. (OD OFF indicator lamp is on.)
• *2: Oil pressure is applied to both 2nd “apply” side and 3rd “release” side of band servo piston. However, brake band does not contract
because oil pressure area on the “release” side is greater than that on the “apply” side.
• *3: Oil pressure is applied to 4th “apply” side on condition *2 above, and brake band contracts.
• *4: A/T will not shift to 4th when OD OFF. (OD OFF indicator lamp is on.)
• : Operates.
• A: Operates when throttle opening is less than specification**, activating engine brake.
• B: Operates during “pro gressive” acceleration.
• C: Operates but does not affect power transmission.
• D: Operates when throttle opening is less than specification**, but does not affect engine brake.
- **: Overrun clutch remains in engaged condition when throttle opening is less than 1/16.
POWER TRANSMISSION
“N” and “P” Positions
• “N” position Power from the input shaft is not transmitted to the output shaft because the clutches do not operate.
• “P” position
Similar to the “N” position, the clutches do not operate. The parking pawl engages with the parking gear to
mechanically hold the output shaft so that the power train is locked.
