I'm askin on behalf of a friend who's drivin wira auto...when the engine is cold(ie after start engine),the gear doesnt shift until when the revving is till 5k.The car seems to be draggin plus feels like no power. But after the engine has warmed up, it's back to normal. It only seems to happen when after just starting up the car. According to one mech, he said gearbox problem.So to make sure askin all ZTH cifus first.TQ.
