When driving on the highway my car feels and sounds like it is in 3rd gear. The cluster display says E and not D which it usually shows. The rpms also are showing 4.5 when I am going 55 or 60 on the highway.
You need a shop to use a scan tool to check the ipc to see if there is a failure. They also need to see if there is a failure in the trans controls which is what I think you have. It is in limp mode right now.
