Fusion Transmission Oil Pressure

Whoa, sounds like a headache! A pressure sensor fault combined with those symptoms definitely points to something serious. Low oil could be the culprit, but it's not the only possibility. Before you just top it off, have you checked for any leaks around the transmission? Also, when was the last time you had the transmission fluid changed? If it's been a while, old fluid can cause all sorts of weirdness with pressure and shifting. That grinding noise is especially concerning though; definitely don't ignore that!

Good points! I haven't spotted any obvious leaks, but I'll give it a closer look tomorrow. As for the fluid change, honestly, I'm not sure when it was last done. I bought the car used a few years back, and I haven't personally changed it. Given the mileage, it's probably overdue regardless. Is it possible that just changing the fluid and filter might resolve the pressure sensor issue, or am I being overly optimistic? Should I also check the pressure switch? I'm trying to gauge how deep I need to dive into this.

Okay, if you're unsure about the last fluid change, that's definitely the first thing to address. A fluid and filter change might help if the old fluid is just gunked up and causing pressure issues. However, the fact that you're getting a specific sensor fault suggests the sensor itself could be failing. The grinding noise really worries me though, as it suggests there is already some level of mechanical damage. I reckon it's time to get it to a workshop for a proper diagnosis. Continuing to drive it in that condition could cause further damage, resulting in a much bigger bill. At least they can properly check the sensor and the overall health of the transmission.

Thanks for the advice! I took it to a trusted workshop, and they confirmed the oil level was indeed low, causing the sensor to throw a code. They also recommended a fluid and filter change, which I went ahead with. Total damage was 365€, but at least the shifting is smooth again, and the warning lights are gone. Hopefully, that's the end of it!
