It could have an effect on shifting if it's out of alignment. There would be a strain on the axles. Get somebody to start it, put in D or R, hold the brake and give it some gas while you look to see if the motor moves backwards or forward a lot. If it moves too much or appears to, it could be the motor mount(s) are broken. Because of torque the engine will try to move and that's what the mounts job is, to keep it in position so everything is where it should be. If the tensioner is against the body something has moved.
