boost monster

Hi all, I had a really strange thing happen this morning on my '10 ralliart w/ 36,000 miles on it. I got in my car, turned it on and backed out of my garage and down my driveway like normal. When I put the car from reverse to drive, the "transmission heating - slow down" warning came on and after about 5-10 seconds changed to transmission service required. As I said a few curse words and drove it back into my garage, I turned it off and back on again. This time, the transmission service required warning stayed on for about 2 seconds and turned off and everything was acting normal. So I decided to drive it to work to see if the warning would come back on but it never did.

Could this have just been an anomaly? Or is it something I should potentially worry about? Thanks in advance for any help on the matter. Last thing I want is for the tranny to go bad in this car.
