RC gearbox slipping

I'm having an issue with my 2019 Lexus RC, gasoline engine, with 186073 kilometers. The gearbox is slipping and shifting uncleanly. I found a transfer case oil wear fault. Could this mean there are defective gears inside the transfer case?

A 2019 Lexus RC is experiencing gearbox slipping and unclean shifting, with a detected transfer case oil wear fault. This issue could be due to defective gears inside the transfer case. An oil change might provide temporary relief, but a thorough inspection is recommended to identify any mechanical issues and prevent further damage.

I had a similar experience with my RC. The transfer fluid seemed to be the culprit. It's like using the wrong type of oil in your engine; it just doesn't lubricate correctly. Have you considered an oil change?

Did your symptoms manifest identically – specifically, the slipping and unclean shifting? Was the oil change enough, or were there mechanical issues in the transfer case that needed more attention?

Yes, the symptoms were very similar. While the oil change helped temporarily, it turned out the gears were indeed defective, like a worn-out cog in a complex machine. I'd recommend having a workshop inspect it thoroughly to avoid further damage.

I will schedule an inspection at the workshop. The repair, including parts and labor, came to approximately 330€. Thanks for sharing your experience; it's been invaluable.
