I've noticed on trips over 30 minutes or so that the right wall of the drivers compartment in my car gets very warm. Because it's basically where the shifter is, I assume it's the transmission that's the culprit. From what others have told me, this is normal. It is, however, something I'd like to correct. There were suggestions on heat wraps for the exhaust and synthetic fluids (amsoil's severe gear) to help with this. How effective is that for prolonged trips (4+ hours). I had never heard of a transmission cooler until running a search here. Assuming I didn't misread, is there a recommended brand?
