check the transmission fluid/oil level. it will have its own dipstick going into the gearbox. check your owners handbook for the correct procedure, as you may need to shift the selector through several positions & then check it in a certain position with the engine running. also the oil should be a nice clean red colour, if its a mucky brown colour or smells burnt, then there may be a problem. check under the car for any leaks, oil/fluid may be getting on the hot exhaust.
