Tundra transmission issues
Summary of the thread
A 2014 Toyota Tundra owner experienced transmission issues, including warning lights, emergency mode activation, shifting problems, and grinding noises. The problem was suspected to be related to a radiator oil pressure error, possibly due to a defective cable, plug connection, oil cooler, overheating, or a bad pressure sensor. A suggestion was made to check the sensor on the transmission cooler line, which led to the discovery of a defective cable as the cause. The issue was resolved with a repair, restoring the vehicle's functionality.

Hmm, a faulty sensor on the transmission cooler line... that's interesting. I was mainly focusing on the radiator itself. Where exactly is that sensor located? And what were your exact symptoms?

Yeah, it was a pain to diagnose. The sensor is near where the cooler lines connect to the radiator. My symptoms were exactly like yours – the lights, emergency mode, the whole shebang. Honestly, I'd take it to a workshop; they'll pinpoint it fast.

Thanks a lot for the tip! I got it checked out, and you were right; it was a defective cable. Cost me 95€ to repair. All working perfectly now!

I had a similar issue with my Tundra. Are you sure it's the radiator oil pressure? When mine acted up, it was a faulty sensor on the transmission cooler line. Did you check the cooling fan?
