Equinox transmission issues

Guys, I'm freaking out! My 2023 Chevy Equinox diesel is acting nuts. I've got 70k km on it, and the transmission is totally messed up. The transmission light and check engine light are both on. It's stuck in some kind of emergency mode, won't shift right, slips like crazy, and makes awful grinding sounds. Plus, the computer threw an error code about the radiator oil pressure being defective. Could this be related? I think it is likely a defective cable. Anyone seen this before?

Summary of the thread

A 2023 Chevy Equinox diesel with 70,000 km is experiencing severe transmission issues, including emergency mode activation, improper shifting, slipping, grinding noises, and warning lights. An error code indicated a potential radiator oil pressure defect, which was suspected to be related to a defective cable. The problem was resolved by addressing a faulty sensor connection, which was fixed by cleaning and reconnecting the contacts.

Did this summary help you solve your problem?

Sounds familiar. I had similar issues with my Equinox. Is your pressure gauge in order? Check your radiator coolant if there are any leakages first.

Coolant level seems okay, and I don't see any obvious leaks. But what do you mean 'pressure gauge'?

Yeah, I had the same thought about leaks, but nothing visible. It ended up being a bad sensor. Probably best to take it to a workshop to make sure. But if you want to try, cable connections are the best place to start looking for failure.

Thanks a bunch! I took it to the shop, and you were right. Turns out it was a faulty sensor connection, just like you said. They cleaned the contacts and reconnected everything and it is good as new. The whole thing cost me 95€!
