Grinding Infiniti Q Transmission Needs Expert Help ASAP

Hey there, I can relate to your transmission troubles. I had similar issues with my 2019 Infiniti QX50 last year. The symptoms you're describing especially the grinding and incorrect gear display sound very familiar. In my case, it turned out to be a faulty wiring harness that was causing communication problems between the transmission control module and the gearbox. When I took it to my local Infiniti specialist, they did a full diagnostic scan. The wiring harness had worn down in several spots, causing intermittent electrical connections. It was actually quite serious since it could've led to complete transmission failure if left unchecked. The repair involved replacing the entire transmission wiring harness. They had to remove the transmission pan to access everything properly. The job took about two days, but it completely resolved all the symptoms the grinding, whining, and incorrect gear readings. If you're in this situation, I'd strongly suggest getting it checked at a certified Infiniti dealer or a specialist who regularly works with these transmissions. These symptoms shouldn't be ignored as they can lead to bigger problems. Hope this helps!

Thanks for sharing your experience that sounds exactly like what I'm going through! Great to know it was fixable. Do you remember roughly how much the repair set you back? And has everything been running smoothly since, or did you run into any other issues?

Hey again! Glad to help! Yes, after getting it fixed at the Infiniti specialist, everything's been running perfectly smooth. The gear selection display is now working correctly what a relief! The total bill came to 180€ for fixing the faulty wiring harness, which honestly wasn't as bad as I was expecting. Haven't had a single problem with the transmission since then it's been about a year now. The grinding noise is completely gone, and the shifting is butter-smooth again. It's like having a new car! Trust me, getting it fixed sooner rather than later was definitely the right call. Just make sure you find a good Infiniti specialist who knows what they're doing. These transmissions can be tricky, but once you get the right mechanic on the job, it's usually a straightforward fix. Let me know if you need anything else!

Thanks so much for all the details! I actually took your advice and went to an Infiniti specialist yesterday. You were spot on about the wiring harness that's exactly what it was! Mine cost a bit more, around 250€, but honestly, it was worth every penny. The mechanic was super professional and explained everything clearly. They even showed me the worn-out parts they replaced. It's amazing what a difference it made no more grinding noises, and the gear display is working perfectly now. The whole repair took about a day and a half. Really appreciate you sharing your experience it gave me the confidence to get it checked out instead of putting it off. The car's running like new again! Thanks again for pointing me in the right direction. It's such a relief to have this sorted before it turned into something bigger! Take care!
