I was wondering why? Once it's in drive and I'm driving down the road the needle just keeps going up and it doesn't like shift through the things. I don't know exactly what it's called so.

Hi,

If the transmission isn't shifting, it could be a few different things. For example, it could be the result of low transmission fluid, a faulty shift solenoid, or the transmission line pressure could be too low.

Because this has several possibilities, what I recommend doing first is having the can-bus scanned. CAN stands for controller area network. Basically, the different modules in the vehicle are tied together via a few wires so they can communicate. This type of scan will retrieve codes regardless of the module storing them.

Here is a link that explains how it's done:

Let me know if that is something you can do. Also, let me know if you have other questions.

Take care,

Joe
