transmission

my 1996 micra auto transmission is tough to change gears and makes a sqeaking noise when i slow down to around ten km hour first thought it was the brakes but they are fine had transmission checked and was all good any ideas on what could be wrong

The following should put the automatic (N-CVT) gearbox into it's self diagnostic test, helping you narrow down any problems you're experiencing.

Self Diagnostic Method:

1. Keeping the ignition off and all pedals released move the selector / gear lever to the "D" position.

2. Turn ignition on - but dont start the vehicle.

3. Depress and hold brake pedal, then fully depress and hold the accelerator pedal.

4. Then move the selector / gear lever in the following order: Ds - D - N - R - P

5. Release the accelerator pedal, then the brake.

6. Start the car...(gear lever still in "P")

7. The N-CVT dashboard warning light will start to blink, count them and compare with the fault code list below)

8. Switch off ignition to stop self diagnostic procedure.

-----------------------------------------------------

The fault code output blinks are made up as follows:

No fault found: There is a 2 second pause, followed by the light remaining on for 2 seconds and then 7 short on/off second blinks.

If a fault is detected one of these 7 short blinks will remain on longer than the others.

Fault Code 1 - The first blink is on longer than the others - Accelerator or accelerator position switch circuit is short circuited or diconnected.

Fault Code 2 - The second blink is on longer than the others - Inhibit switch circuit is short circuited or diconnected.

Fault Code 3 - The third blink is on longer than the others - Vehicle speed sensor circuit is short circuited or diconnected.

Fault Code 4 - The fourth blink is on longer than the others - electro-magnetic clutch coil circuit is short circuited or diconnected.

Fault Code 5 - The fifth blink is on longer than the others - Line pressure solenoid circuit is short circuited or diconnected.

Fault Code 6 - The sixth blink is on longer than the others - Torque signal circuit is short circuited or diconnected.

Fault Code 7 - The seventh blink is on longer than the others - ABS signal or idle up relay circuit is short circuited or diconnected.

Fault Code No Number - Lamp blinks at 4Hz repeatedly - Battery supply fault or memory back-up fault.

Fault Code No Number - Lamp does not blink - Check all components.


The squeaking your experiencing at certain speeds is pretty common which could indicate the belts inside the box.
I would also check the fluid level.

Where abouts are you located mate?

thx jon tryed that no luck everything is ok central coast in nsw doom think i might need a new transmission

you could check the carbon brushes just for good measure.

does any body know how i can check the carbon brushes thx for the tip david

they bolt onto the front i believe shane

frank

the thing pictured above bolts straight into the front top (of the engine/transmission block)slightly to the right of the battery holder in the right hand drive models. I will try to find pics if u need.
