Failing Gear Display Linked to Transmission Problems

Got some experience with this, had a similar issue on my 2010 Chevy Cruze, and I've worked on several GM models over the years. The electronic display and gear indicator problems you're describing sound exactly like what I dealt with. My car dashboard started showing incorrect gear positions, and the transmission began acting erratically. Turned out the gear shift control unit was failing, affecting both the display and actual transmission operation. Had to get it fixed at a shop, cost around 1000 for the complete repair. The main culprit was a defective control unit that manages both the gear indicator and transmission communication. The grinding and slipping stopped completely after replacement. Before suggesting specific solutions, would be helpful to know: Any warning lights on the dashboard? Does the gear shift knob feel loose or different? When exactly did these symptoms start? Have you scanned for error codes? Would like to share more detailed info based on your specific situation, since these symptoms can sometimes point to different root causes in different model years.

Had my latest service at 66732 KM, and the technician found the shift knob sensor was completely shot. After testing the automotive electronics, they confirmed the sensor problem was causing both the digital display malfunction and the transmission issues. The instrument panel errors started showing up about 2 weeks before the entire system began acting up. Replacing the faulty sensor unit and recalibrating the transmission control module fixed both the gear indicator and the rough shifting. Total repair cost was reasonable, much less than replacing transmission components. Got all the error codes cleared, and everything's working smoothly now. If your symptoms match mine, definitely have them check the shift position sensor first before looking at more expensive transmission repairs.

Thanks for sharing your repair experience, that's really helpful info! Had almost the exact same repair journey with my Chevy. The sensor problem started with just the digital display acting up, then quickly spread to actual transmission behavior. My shift knob sensor also failed completely around 70K km, causing both the gear indicator issues and transmission problems you described. The electronic display malfunction was definitely the first warning sign, wish I'd caught it sooner before it started affecting the actual shifting. One thing I learned: these sensor failures tend to get worse fast. Once the gear indicator starts showing wrong positions, it's usually just a matter of time before the transmission control gets confused too. The good news is the sensor replacement is way cheaper than transmission work. Quick tip for others reading: if your gear indicator starts acting up, get the shift position sensor checked ASAP. Much better to catch it early when it's just a display issue rather than waiting until it affects the whole transmission system.

Thanks for confirming my suspicions about the sensor being the root cause. It's a relief to hear your repair costs were reasonable. Those unusual gear slips and grinding noises had me worried it might be major transmission damage. My gear indicator is working perfectly now after the sensor replacement. The electronic display shows the correct gear position every time, and the transmission shifts smoothly again. Really glad I didn't wait longer to get it fixed, could've ended up with more serious problems. For the record, my error codes were P0706 and P0707, which directly pointed to the shift position sensor failure. The automotive electronics diagnostic really helped pinpoint the exact issue. Having the transmission control module recalibrated as part of the fix was key to getting everything working properly again. Big difference in how the gear shift feels now too, much more precise and responsive. No more guessing which gear I'm actually in!
