I just got the vehicle listed above and the transmission is not working right. So I took it to the transmission shop and they replaced some parts and it worked okay for a week and now it's doing the same thing and the same code the 3-4 shift code. I don't know what the problem is. I mean I work on older cans and it's not the same. So can you help me?

Hello, I'm Danny.

The best thing for you to do first is perform a CAN scan. A CAN- Controller Area Network scan will test and retrieve all codes that are stored in your vehicles computer. This scan will test all systems on your vehicle including the transmission. Here is a tutorial showing how to perform this scan:

Due to the numerous components in the transmission it could be numerous different things causing this issue. After you perform this scan get back to us with any and all fault codes and we can then properly diagnose all the issues with your vehicle including the transmission. Hope this helps and thanks for using 2CarPros.
