I bought a Mazda 3 2012 new and the first few miles off the lot and for a short time on the freeway, I was driving in manual mode (mazda 3 automatic transmissions have a manual mode also) without realizing it and only noticed it when I started to accelerate. Anyway, since I was on the freeway, I couldn't slow down and was driving in a low gear for a couple of minutes and since then, it doesn't feel like the car accelerates as it should (kind of sluggish). Is there a chance I damaged either the engine or the transmission? How would you go about diagnosing if there is a problem?
