Customer Question

2006 Range Rover sport, sub was driving fine last night but when I got in tonight it's reading transmission fault: limited gears available, and it's stuck in park.

Hello and welcome to JustAnswer!

You're seeing the warning because the trans controller either isn't awake or it has seen a failure and has put the trans in limp in. Being locked in park usually indicates a power feed to the trans controller has been lost or the controller itself has failed. The trans controller is an integral part of the valve body in the trans.

If fuses are good then what will need to be done is use a scan tool to see if the trans controller communicates. If not then it's power and ground feeds as well as communication bus voltages will need to be checked before condemning the TCM/valve body.

If the TCM is actually awake then there will be stored fault codes that will need to be used as a starting point for diagnosis.

I turned the car off and set the alarm twice. Afterwards I started the SUV and the fault message was removed, however the check engine light was still on. After driving the vehicle for 19minutes the check engine light disappeared and my SUV drove fine. Should I still be worried?

I would still at least see what fault codes had set. Sometimes electrical problems come and go without ever happening again but odds are the problem will return if it isn't repaired.
