This is indicating that the computers have detected a fault with one of the transmission components.This most likely failed on key on when you hopped back in and turned on the key or before the key was turned on.
What has to be done from here is to have the fault codes read out/checked using a fully compatible scan tool that can plug into your vehicle and can read all computers to see what codes are set.Once this is done any codes set then need to be diagnosed to then locate and repair this issue here.

This is definitely an intermittent component at fault in the transmission then.This can be a sensor like the transmission fluid temp sensor or another sensor acting up sending an intermittent false signal.I have seen sensors cause this issue here.
Even though the fault has cleared up if it does occur again the best thing to do here is to have the fault codes read out/checked right away to see what codes are setting then those codes can be diagnosed to correct the fault permanently.A local parts store will read the codes free of charge to you.

The check engine light will come on when a fault is detected with the engine or transmission.So it came in relation to the transmission fault that was detected.This does indicate the fault codes do need checked.
