Check engine oil light, check engine light and open door in the same day

first i would check the engine oil level.then for the door message being on/open,most likely a stuck door ajar switch.probably the drivers door,since it's used more than other.spray WD-40 in the door switch/switches,open and close door/doors several times to free up stuck switch.AAMCO will do a diag. test on your transmission at no charge.
