Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

When that light comes on, codes have been stored in the computer. We then need to find out what they are with a code reader or a scan tool. Most parts stores will read the codes for you for free with a code reader, but they can't give you data that you need to know like a scan tool can.

get the codes read and let me know what they are. If the car still drives okay, it may be fine for you to drive a short distance.

Thanks, Ron

The truck drives fine, it just will not go any higher than 4th gear regardless if I use the sport shift and try to go to 5th or 6th. With that it runs around 2000 rpm around 45 to 50 MPH. It will be a slow ride wherever I go.

Okay, it's in limp mode. You need to get the codes read and let me know what they are.

I ended up towing thevehucle and i was not told the error codes but it was found that a critter got under my hood and chewed through a wire harness connector. I was told thankfully it is not the main motor harness and the part is $35.
