AH malfunction while doing 80-95...

I was just driving on the freeway a little more aggressive than usual commutting and when I hit 3rd to 4th, the AH came on the DIC and said "System Error" /phpBB/images/smiles/icon_confused.gif or something and then said "TC On" but the TC light was on too. So I just hit the AH button and everything went back to normal. Took it easy home.

It seems like everything is OK, but will this happen again....when I need it..?

Has this happen to anyone else?
Should I take her in?

Thanks everyone.

Hi there,
Curious if there were any codes stored in either instance?????
Any fault, will set some kind of code, even if it is a wiring failure.
Best to all, c4c5
Thats ok, no problem with that.
Due to the communication process within the PCM, it controls the others, and will set this code.
It is classified as normal by the the engineers at GM.
Take care, c4c5
