Tranny trouble

[colzie]

Hi Guys and Gals

I have a little Nissan Micra 1300 auto K11 model.I left the car in my garage for four months as I was using a different car.I went to start the Micra and she started no problem but for some unknown reason to me the car will not go forward or backwards when these gears are selected The reverse light comes on when reverse is selected and the warning bleep you get when the car is in gear and a door is ajar are both working fine.


When I put the car in the garage there were no such issues.Anyone know what might be causing this?I have checked the AT fluid and it is fine and the control cables running to the gearbox are also free and moving.

Any advice would be appreciated.

Cheers Colzie

Hi Colzie,

the gearbox in your car is a NCVT. they work off a electromagnetic clutch system. The clutch unit is filled with iron fillings, when you put into gear the contacts energize the clutch and the fillings are magnatized and the clutch is engaged. (technical stuff)
there are not many things you can check yourself, you have done just about all you can with checking the oil etc.
Is the gear lever hard to move into gear? (if so your clutch may be worn out)
Is the gearbox warning lamp on?
It could just be that the contacts on the clutch unit have corroded and not making good contact.
if you wont to check this you will need to remove the contacts. this can be done easy.
open the bonnet, at the front of the gearbox you will see a plate with 2 wires and 2 bolts. undo the 2 10mm bolts and unplug the wire connector. remove the contacts and check there condition. than you can see inside the gearbox and check the clutch contacts also.

hope that makes some sence.
