Code P0902, possible transmission issues?

My friend has this car and about 2 weeks ago the check engine light came on and she said the car "didn't want to go". I plugged in a code scanner and got P0902. I cleared the error, and she says it's been fine since.

Today she says when she cranked it up, the traction control light was on, but it went off after driving a few minutes. No check engine light this time.

Could this be a sign of imminent transmission failure, or could it be easily fixed? I'm not too familiar with Ford myself.
