With a bumper to bumper warranty, If I think something is wrong with my car, can I just bring it in?

With a bumper to bumper warranty, If I think something is wrong with my car, can I just bring it in at anytime to get it checked? Or does something need to be wrong with it first before i bring it in? Because I just bought a car and at 2400 miles the tranny seems to already lag while shifting.|||You should be covered, you don't know if something is wrong or not. If it's an automatic then it may be natural for it to lag when shifting if your stepping on the throttle, but if it's a manual then maybe your just not engaging the clutch fast enough.|||Take it in and have them check it out.Can't hurt?
