i started it and drove it aabout  200ftbut the light still is on. also how to check the gearbox fluid levels

Answer
The gearbox fluid is checked when the vehicle is running on a lift.  You check it from below while someone is in the car going through the gears.  Read the procedure at www.landrovertechinfo.com but it's not a do-at-home task for most owners.

As to the light - you will need a shop with the specialized Land Rover test system to read it.  The generic OBD II scan tools can't talk to the transmission.

Look at www.rangerovers.net for shop recommendations.
