Seeking Advice on 2019 Nissan Murano's Suspected Transmission Control Unit Issue and Gear Shifting Problems

Hey there, I've dealt with a similar issue on my 2017 Nissan Rogue, same brand and a couple of years older. I've got some experience with cars, not a pro, but can handle my way around. When I felt weird transmission and gear shifting issues, I took my Rogue to the local workshop. Turned out, you're spot on, it was a faulty Transmission Control Unit (TCU). The guys at the garage were solid and sorted it all out - but it did set me back 1000 Euro to get the TCU replaced. For your Murano, can you share a few more details - like any specific events when these issues happen, any dashboard warning lights, how's the overall engine performance and mileage? Let's crack this nut together!

Hey, thanks for sharing your story! Glad to hear you successfully managed to get it fixed. You're correct about wanting more specifics. These slips and noises seem to occur most often during uphill drives or when I accelerate rapidly. No warning lights on the dashboard so far, which I found really strange. As for the engine, it's been performing as usual, doesn't seem affected by these gear issues. Mileage-wise, she's done a good 190501 KM run, and I had a regular service not long ago. Hoping to find a way out of this without shelling out loads of cash. Fingers crossed!

Hey there again! Appreciate all of the extra details. Your situation seems pretty similar to what I faced. Typically, the TCU issues can cause these kinds of uphill drive or rapid acceleration problems. It's a tad strange there aren't any warning lights, but sometimes these electrical issues can be sneaky like that. On the bright side, at least the engine isn't suffering. With your mileage and recent service, I reckon it would definitely be beneficial to get the TCU checked just to rule it out. If it is the TCU, it may take a bit of investment to replace it, but you'll save on eventual costs of more serious damage if left unchecked. Still, before you head to the workshop, have a friend or someone with decent car knowledge take a look at your vehicle's transmission fluid. If it's low or dirty, it could cause the kind of problems you're experiencing without a costly component replacement. And if it turns out to be the TCU after all, don't worry too much. It's a common issue and usually doesn't recur once fixed. Keep your fingers crossed! Let's hope it's just a minor fluid issue.

Aye, sound advice you're giving! Hadn't thought about inspecting the transmission fluid. I've got a friend of mine who knows a thing or two about cars - gonna get him to give it a look-see. If the fluid's all good, I'll then consider getting the TCU assessed at the workshop. A bit tough on the wallet but you're right, better safe than sorry. Thanks again for all your input! You've definitely lightened the load on my mind. I'll hope for the best and keep my fingers crossed. Cheers!
