Intermittent Check Engine Light...Transmission Related.

[FlaAveo5]

The 'check engine light' comes on....when I miss coming to a total stop. And then I 'gun it'...to move fast from a near stop, like doing a 'rolling stop'.....you know what I mean.

Then I hit the gas it is SEEMS to drop a gear,like normal, to rev up....and the light comes on. It just strikes me as odd. Is it??? It clears itself on its own in 1-3 days. But has anyone had this happen to them??. Wondered if it is odd or this is what happens???
