my wifes 06 hhr t/c light came on getting on the freeway, it shifted oddly but kept going ok. then a mile down the street the check engine light came on. autozone said code p0102 came up and p0113, after messing with the aircleaner the codes cleared up, sounds crazy to me? what would be up with it? why doesn't the car have a trans dipstick, I can't find one? thanks any ideas?
