Seeking Advice on 2018 Fiat Mobi Gasoline's Erratic Shifting and Grinding Noise Issues

Hey there, sorry you're dealing with this headache - sounds frustrating. A couple of years back, I had some similar trouble with my trusty 2016 Fiat Uno. I'd put myself down as having some experience with cars, nothing pro-level though. Turned out the problem was with the transmission control unit. Made the same grinding noise too. Had to fork out around 1000 Euro for the fix, as pricey as a vintage wine. Just a quick question, though... did you notice if this issue is happening regularly or just with specific gear shifts? That info could help point out if there are more potential issues to consider. Cheers!

Hey, yeah, it's a total headache indeed! The issue is more predictable than you'd think - happens mostly when shifting from 2nd to 3rd. Hoped it was just a rough patch but the problem's glued on. By the way, I bought it pre-owned, just passed the 102499 km mark last week. Last service was pretty recent though, so everything else should be in tip-top condition. Your insight makes it sound like Transmission Control Unit might be the real culprit. A 1000 Euro is a lot, but guess it's better than risking more damage, right? Thank you for the help! Cheers!

Hey, gosh, the whole 2nd to 3rd gear issue strikes a chord – it was almost the exact same scenario with my Uno, so it very well might be Transmission Control Unit kicking the bucket. One thing to bear in mind though; fix could still be cheaper than the 1000 Euro I paid - It's been a few years and my Uno's model is older, so parts pricing can differ. And yeah, you're spot on. It's a bit of an outlay, but it beats causing more damage over time. You know what they say, pay now or pay double later (in stress as much as cash!). Plus, when it's fixed, you'll definitely enjoy the seamless gear shifts again. Hang in there! Cheers!

Hey, that's some great news! Well not "great", but you get what I mean. Helps knowing someone else had an almost identical problem. Sounds like I've got my culprit. You have a good point about the cost - fingers crossed it doesn't go to the high side. And you're absolutely right, rather a bit of a dent in the pocket now than a total car havoc later on. Who needs that stress, right? Going to reach out to my local workshop and see what they say. Really appreciate your help made my day less stressful already! Cheers!
