Understanding your transmission could save you a lot in repairs, yes automatic are easy to drive but driving in drive all the time may not be the best for it. Of course Transmissions shops love it when you do so they can charge a fortune to fix. Just good to know your car and what options you have. I use my transmission to slow down with in snowy conditions. I also don’t drive around the city in drive usually will use a lower gear so my engine is not lugging.
