NX transfer case oil wear fault
Summary of the thread
A 2016 Lexus NX hybrid with approximately 127,993 km is experiencing gearbox slipping and unclean shifts, suspected to be due to a transfer case oil wear fault. The absence of visible oil leakage suggests the issue might be related to old or low transfer case fluid. While an oil change could address fluid-related problems, defective gears would require professional inspection and repair. Ultimately, the gears in the transfer case were confirmed to be defective, necessitating repair at a cost of around 330€.

No visible oil leakage. I haven't touched the transfer case oil since I bought it. I was planning to do an oil change, but could this be the only problem? Is the oil change really gonna fix defective gears?

Right, no leakage is good, but old fluid can still cause problems. Honestly, if the gears are truly defective, an oil change won't fix that. I'd get it checked out at a workshop to confirm, but it does sound like it could be a similar issue I had. Ended up costing around 330€ to sort it.

Thanks! I really appreciate the advice. I went to the workshop, and you were spot on. Turns out the gears in the transfer case were defective. They're getting it sorted now. Costing me about 330€ too!

I've got an NX too, and that sounds familiar. Is it leaking any oil? When was the last time you had the gear oil or transfer fluid changed? Could be something as simple as low fluid.
