Qashqai Transmission Control Unit Failure

I'm having serious issues with my 2006 Nissan Qashqai diesel. It's got about 215929 km on the clock. The paddle shifters don't work anymore, the gearbox slips, and it makes awful grinding noises when shifting. It's also very slow to respond, and sometimes goes into emergency mode. I had the error memory read, and it points to a defective transmission control unit. Has anyone else had similar transmission problems?

Sounds familiar. I had similar symptoms on my Qashqai. Does it feel like the gearbox is just generally not behaving itself? For me it turned out to be the car computer, the transmission control module specifically. Was that also what your error code said?

Yes, that's exactly what the error code indicated: a defective transmission control unit. It's good to know someone else has experienced this. How did you resolve it? Was it a simple fix, or did it require a full replacement?

Unfortunately, there's no simple fix for that. Affected control units are usually defective and need replacement. I ended up having to take it to a workshop. Cost me around 1000€ to get it sorted, but it fixed all the issues. I would suggest you do the same.

Thanks for confirming my fears, but I appreciate the advice! I was hoping it wouldn't be a costly repair, but at least I know what to expect. I'll book it into a workshop and get the control unit replaced. Thanks again for sharing your experience!
