Nissan Micra K11 auto CVT (1995) - CVT auto gearbox Issue – No drive or gears - Nesty

Hi All

I have a gearbox issue, enroute on way to work this morning, my Micra K11 cut out, (gearbox fine at this point), thought might be damp, I tried re-starting no avail, so cruised in neutral to a safe place, then placed gearbox in park mode.

I waited about 2 minutes engine started fine, set off but gearbox judder / whine, got about 800m down the road pulled in to a layby, then used reverse to straighten up, though gearbox whining, went to select D, now absolutely nothing in all gears.

Though when you place in D, you don't get that engage feel (like that small jolt, feel of engagement), just nothing happens.

The CVT light is not on. The gearbox done 130,000, but had regular oil changes.

Any ideas what this could be? I was wondering, if I placed it in P mode, whilst wheels were not stationery, has possibly screwed it up?

This uses an electromagnetic clutch system. It’s possible the contact brushes have worn out. Also check the fuses in the box next to the battery . Anything beyond that is likely to be an uneconomic repair .

The brushes that supply the current to the clutch are in a unit that is mounted to the flywheel housing.

When I had a K11 auto at about 37k miles I pulled it to check them that's how I know.

The ECU for the transmission and clutch is in the lower centre of the dashboard centre console.

Here's a how to do it blog with pics.

I don't know how reliable replacing the oem brushes with alternator brushes is though!

Many thanks for the replies, these gearboxes seem very complex, as mentioned has to be straightforward fix, as anything other be worth much more than the car worth.

The car been a decent servant!
