Hello. Seeking advice on 2010 IS250 automatic RWD transmission woes. Downshifts from 2 to 1 very hard. I've seen 2-3 online suggestions it could be ECU/PCM. Should this be a first consideration? This is the first issue I've had with car. I'm original owner; transmission & engine have never been “opened." Has two lights: the check engine & Trac light; two codes are generated: P2757 & P2714. I appreciate your help. Gus
