Problems with the transmission of a 2019 Mercedes GLE Class - possible defect in the transmission oil pressure cooler

Hello everyone, I have a problem with my 2019 Mercedes GLE Class with gasoline engine. The gearbox is acting up somehow, sometimes slipping and sometimes shifting strangely. I also hear a strange grinding noise when changing gear and a whining or grinding noise. I thought it might be the transmission oil pressure cooler. Has anyone gone through the same thing and could give me a tip on what was done in the workshop? Really grateful for any help!

Hi, I had a similar problem with my 2017 Mercedes GLC. I have some experience with cars, but I'm not an expert. In my case it was the cable connection valve that was faulty. The repair at my garage cost 1 euro. It's probably best to have it checked at a garage just to be sure. Do you happen to know if your car has ever had the gearbox oil changed? That could also be the problem. Hope this helps you!

Thank you for your answer! The gearbox oil was already changed at the last service (at 825 km). So it wasn't that long ago. I think I'll take my car to the garage and have the cable connection valve checked. You never know. Thanks for your advice!

No problem, I'm glad I could help! Yes, that's a good idea. Best to have it checked at the garage to be sure. Servicing can be tricky sometimes, and it's always better to be safe than sorry to avoid potential future problems. Good luck, and let us know how it went!
