Down shifting an automatic tranmission at normal driving....down a hill ect ect will not hurt anything. Holding it in a particular gear at wot will hurt it.
well yeah i dont leave it in first gear. i will shift it when the rpms get too high or when it would normally shift. i just get bored of leaving it in drive the whole time so i downshift every now and then. thank you for not leaving a smart a** reply.
