Jeeze, talk about splitting hairs here... As was already stated, your transmission won't die a premature death because you (gasp!) used one of it's built in features. My wife's car has 284,000 miles on it with the original transmission. Since we have a flat driveway and she parks in a flat parking lot at work, she actually has to use reverse to navigate to the road. Every day, multiple times a day. Still works... Not sure how though?
