I can’t speak about transmissions but I love my warming seats up here in WI . However to me it’s a luxury because it’s the first car I’ve owned w them. But for a transplant from a warm climate may he a necessity
However, now that I have a 6 minute commute they won’t warm up by then
if she is like me doesn’t have time to warm up car for more than 3 minutes. I just dress warm.
