Tundra transmission issues

I'm having trouble with my 2014 Toyota Tundra with a gasoline engine. It only has 55705 km on it. The transmission indicator light and check engine light keep coming on. The automatic transmission goes into emergency mode, doesn't shift right, slips sometimes, and makes a grinding noise when shifting. I scanned it, and there's an error stored related to the radiator oil pressure. Could a defective cable or plug connection of the component be the problem? I'm wondering if it might be related to the oil cooler, or maybe the car overheating, or even a bad pressure sensor.

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.

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?

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!
