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-473, "
Checking A/T Fluid".
A/T Fluid Cooler CleaningINFOID:0000000001731917
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".

Adjustment of A/T PositionINFOID:0000000001731424
Move selector lever from “P” position to “1” position. You should be able to feel the detents in each position. If
the detents cannot be felt or if the position indicator is improperly aligned, the control cable needs adjustment.
CAUTION:
Make sure that parking brake is applied before adjustment.
1. Remove the air duct assembly. Refer to EM-27, "
Removal and Installation".
2. Remove the control cable nut (A) and control cable (1) and
place the manual lever (2) in the "P' position.
3. Place selector lever in “P” position.
4. Hold control cable (1) at the end and pull it with a force of 9.8 N
(approximately 1 kg, 2.2 lb). Release the control cable and tem-
porarily tighten control cable nut (A).
5. Tighten control cable nut (A) to the specified torque.
CAUTION:
Secure manual lever when tightening nut.
6. Move selector lever from “P” to “1” position again. Make sure that selector lever moves smoothly.
7. Check A/T position. Refer to TM-497, "
Checking of A/T Position".
8. Install air duct assembly. Refer to EM-27, "
Removal and Installation".
Checking of A/T PositionINFOID:0000000001731425
1. Place selector lever in “P” position, and turn ignition switch ON (Do not start engine).
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm selector lever stops at each position with the feel of engagement when it is moved through all the
positions. Check whether or not the actual position selector lever is in matches the position shown by the
shift position indicator and the transaxle.

INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
 When replacing an engine or transmission you must make sure any dowels are installed correctly
during re-assembly.
 Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.
 Do not reuse O-rings and copper washers. Refer to TM-503, "
Exploded View".
 When turning crankshaft, turn it clockwise as viewed from the front of the engine.
 When tightening the bolts for the torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-50, "
Removal and Installa-
tion".
 After converter is installed to drive plate, rotate crankshaft several turns to check that transaxle
rotates freely without binding.
 When installing the transaxle to the engine, align the matching mark on the drive plate with the matching
mark on the torque converter.
 When securing the transaxle assembly to the engine, attach the
bolts in accordance with the following standard.
(A): A/T to engine
(B): Engine to A/T
 Align the positions for the bolts on drive plate with those of the
torque converter, and temporarily tighten bolts. Then, tighten bolts
to the specified torque.
 After completing installation, check for A/T fluid leakage, A/T fluid
level and A/T positions. Refer to TM-171, "
Checking A/T Fluid" and
TM-497, "
Checking of A/T Position". Dimension A: 16.2 mm (0.638 in) or more

12. Check foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.
If frictional material is detected, clean the A/T fluid cooler
after repair of A/T. Refer to TM-172, "
A/T Fluid Cooler
Cleaning".
13. Remove magnets from oil pan.
