Veloster Transmission Indicator Light Issue

Whoa, sounds rough! I had a similar issue with my old Opel Insignia – different car, I know, but the symptoms ring a bell. My transmission was acting up, throwing all sorts of errors. For me, it turned out to be a defective connection, some chafed cables near the pressure sensor that messed with the whole system. These sensors are there to read the pressure, and if the connection is bad, the readings will be wrong and the system reacts to the wrong readings. It put the car into limp mode, which is a kind of emergency mode, to protect the transmission from further damage. Have you checked the cable connections around the radiator and transmission? It might be something simple like that.

Thanks for the quick reply! When you say 'cable connections,' are we talking about the ones directly connected to the radiator, or are there other ones near the transmission I should be looking for? I'm not exactly a mechanic, so any extra detail would be super helpful. Also, how easy was it to spot the chafed cables? Did you need any special tools or just a good flashlight and some patience?

Okay, so on my Insignia, the problematic cable was near the radiator, but it was specifically related to the transmission cooler lines that run to it. So, start there. It was a bit of a pain to see, honestly. I used a flashlight and a small mirror to get a better view of the connections. The chafing was visible once I found the right spot – the insulation was worn away, exposing the wires. You can check the cables by checking to see if they are properly connected. If you are not a mechanic, you should leave it alone and bring it to a workshop. If they find it and fix it, it will probably not cost the world.

Just wanted to say thanks for the advice. I took it to a shop, and they found a defective cable or plug connection, like you suggested! Total repair cost was only 95€ - a lot better than a new transmission! You saved me a ton of money and stress, I really appreciate it!
