Transmission stuck in fifth gear

Welcome to 2CarPros.

It sounds like the shifter linkage has come apart or disconnected at either the transmission or in the vehicle. I just searched for twenty minutes and can't find a picture of the linkage. However, put the parking brake on and block the wheels. Then you will need to crawl under the vehicle and inspect the linkage that attached to the transmission to see if something has come disconnected or has broken. You should have a helper in the vehicle with his foot on the brake while under the vehicle and also, have them shift through the gears to confirm movement in the linkage. If you see something disconnected and are not sure if it is the problem, up load a picture for me to see.

Let me know if I can help.
