Adjustment of A/T PositionBCS0014X
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 pointer indicating the position is improperly aligned, the con-
trol cable needs adjustment.
1. Place selector lever in “P” position.
2. Loosen control cable lock nut and place manual shaft in “P”
position.
CAUTION:
Turn wheels more than 1/4 rotations and apply the park
lock.
3. After pushing the control cable with the specified force, move
your hands off the control cable.
4. Connect control cable on manual shaft.
CAUTION:
No application of a force to the manual lever.
5. Tighten control cable lock nut.
6. Move selector lever from “P” to “1” position again. Make sure that selector lever moves smoothly.
7. Apply grease to contacting areas of selector lever and control cable. Install any part removed.
Checking of A/T PositionBCS0014Y
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 transaxle body.
5. The method of operating selector lever to individual positions
correctly should be as shown in the figure.
6. Confirm back-up lamps illuminate only when lever is placed in
“R” position. Confirm back-up lamps do not illuminate when
selector lever is in “P” or “N” position with selector lever pushed
against “R” position.
7. Confirm engine can only be started with selector lever in “P” and
“N” positions.
8. Make sure transaxle is locked completely in “P” position.Specified force: 9.8 N (1.0 kg, 2.2 lb)

Completely remove all moisture, oil and old sealant, etc.
from the transaxle case and converter housing mounting
surfaces.
6. Tighten oil pump fitting bolts to the specified torque. Refer to AT-
246, "Components" .
7. Install O-ring to input shaft assembly (high clutch drum).
8. Adjust brake band according to the following procedures.
a. Tighten anchor end pin to the specified torque.
b. Back off anchor end pin two and a half turns.

CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.

When the compressor is removed, store it in the same way at it is when mounted on the car. Fail-
ure to do so will cause lubricant to enter the low-pressure chamber.

When connecting tubes, always use a torque wrench and a back-up wrench.

After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.

When installing an air conditioner in the vehicle, connect the pipes at the final stage of the opera-
tion. Never remove the seal caps of pipes and other components until just before required for con-
nection.

Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.

Thoroughly remove moisture from the refrigeration system before charging the refrigerant.

Always replace used O-rings.

When connecting tubes, apply lubricant to circle of the O-rings shown in illustration. Be careful
not to apply lubricant to threaded portion.

O-ring must be closely attached to the groove of tube.

When replacing the O-ring, be careful not to damage O-ring and tube.

Connect tube until a click can be heard, then tighten the nut or bolt by hand until snug. Make sure
that the O-ring is installed to tube correctly.

After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then
tighten connections of seal seat to the specified torque.
Precautions for Servicing CompressorBJS000F8

Plug all openings to prevent moisture and foreign matter from entering.

When the compressor is removed, store it in the same position at it is when mounted on the car.

When replacing or repairing compressor, follow “Maintenance of Lubricant Quantity in Compres-
sor” exactly. Refer to AT C - 2 1 , "
Maintenance of Lubricant Quantity in Compressor" .

Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with lubri-
cant, wipe it off by using a clean waste cloth moistened with thinner.

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.Lubricant name : Nissan A/C System Oil Type S

REFRIGERATION SYSTEMPFP:KA990
Refrigerant CycleBJS000FF
REFRIGERANT FLOW
The refrigerant flows form the compressor through the condenser with liquid tank, through the evaporator, and
back to the compressor. The refrigerant evaporation in the evaporator is controlled by an externally equalized
expansion valve, located inside the evaporator case.
FREEZE PROTECTION
To prevent evaporator frozen up, the evaporator air temperature is monitored, and the voltage signal to the
unified meter and A/C amp. will make the A/C relay go OFF and stop the compressor.
Refrigerant System ProtectionBJS000FG
REFRIGERANT PRESSURE SENSOR
The refrigerant system is protected against excessively high- or low-pressure by the refrigerant pressure sen-
sor, located on the condenser. If the system pressure rises above, or falls below the specifications, the refrig-
erant pressure sensor detects the pressure inside the refrigerant line and sends the voltage signal to the ECM.
ECM makes the A/C relay go OFF and stops the compressor when pressure on the high-pressure side
detected by refrigerant pressure sensor is over about 2,746 kPa (27.46 bar, 28 kg/cm
2 , 398 psi), or below
about 134 kPa (1.34 bar, 1.4 kg/cm
2 , 20 psi).
PRESSURE RELIEF VALVE
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.
When the pressure of refrigerant in the system increases to an unusual level [more than 3,727 kPa (37.27 bar,
38 kg/cm
2 , 540 psi)], the release port on the pressure relief valve automatically opens and releases refriger-
ant into the atmosphere.
