Nissan Pathfinder '04 Transmission Issues and Suspected Faulty Oil Pressure Sensor

Hey folks, I've got a bit of a headache with my '04 Nissan Pathfinder (gasoline, 104082 KM). Lately, I've noticed the transmission slipping and shifting oddly, some nasty grinding noise when switching gears, and a warning light in my speedometer. I had a bad run-in with the mechanic last time so I'm a little lost here. I'm speculating it might be a faulty transmission oil pressure sensor. Has anyone here dealt with something similar? I'm eager to hear your experiences with this issue and how your mechanic handled it. Cheers!

Summary of the thread

The conversation revolves around transmission issues in a 2004 Nissan Pathfinder, characterized by slipping, odd shifting, grinding noises, and a warning light. The initial suspicion is a faulty transmission oil pressure sensor. However, a similar experience with a 2007 Nissan Xterra suggests the problem might be due to low transmission oil levels. The recommended solution involves draining and refilling the transmission fluid, resetting the ECU, and fine-tuning the transmission, which resolved the issues in the Xterra. The advice is to check the transmission oil level and consult a reliable mechanic for a thorough inspection.

Hey, I reckon I can relate to your issues. I drive an '07 Nissan Xterra and a couple of moons ago, I got hit with the same issues - odd shifting, grinding noises, all that jazz. I zeroed down on it being a 'transmission oil level too low’ matter, not a faulty transmission oil pressure sensor. My garage guy checked out the car and confirmed my hunch. He believed this was a serious issue, and he wasn't just blowing smoke. He explained that neglecting such transmission issues could lead to major repair works down the line, or worse, a burnt-out transmission. So, here's what went down. He had to drain the existing transmission oil, fill it up with fresh transmission fluid, then reset the ECU to handle the new fluid, and finally fine-tune the transmission. This whole process helped in getting rid of those weird noises and grinding. I'm just a guy who had a similar issue, and this was my adventure at the garage. Might be a good idea to have your Pathfinder checked out for a transmission oil issue. Hope this helps and you get your Pathfinder back on track quickly. Cheers!

Hey there! That's some real useful info you're dropping! My Pathfinder's symptoms seem strikingly similar to what you experienced with your Xterra. Out of curiosity, do you happen to remember what sort of dollars you had to part with to get your ride back in tune? Also, since getting the work done, have there been any further problems or was it smooth sailing from there on? Cheers!

Hey! I'm glad the info was useful. To answer your question, I had to say goodbye to 365€. But on the bright side, since the mechanic showed the transmission some love, my Xterra’s been near as perfect, no problems at all. The whole transmission oil pressure sensor scare turned out to be a lamb in wolf's clothing! He fixed the low transmission oil state and the pressure sensor malfunction in one go, and it's been as smooth as butter ever since. Goes to show the right care can bring your ride back from the dead, eh? Fingers crossed that your Pathfinder gets back to her prime soon too! Cheers!

Hey! Thanks heaps for all the info and honesty. I reckon 365€ isn't a nightmare if it helps my trusty Pathfinder get back to her glory days. I'm relieved to hear your Xterra's running shipshape since the fix. I guess it's about time I hunt for a reliable mechanic to sort this out. Cheers to the smooth rides ahead! Gonna run a check on the ol' girl's transmission oil and make sure she's got enough juice. Thanks again for your guidance. A toast to trouble-free vehicles and helpful folks like you! Cheers!
