Was this the oem gauge?
If so, good to know it goes higher than 199 F...I was on a long drive up north and it was like ~97 F the whole way and the temp stayed at 199 F the entire way (only doing 75-80 though) and thought maybe it didn't read higher, lol, as that was weird. Otherwise, it stays pretty cool most of the time, relatively speaking, according to the gauge.
However, if I were concerned, I wouldn't rely on the oem gauge...over 200 F does sound sort of high though, but not sure in a damaging way, just wouldn't be comfortable with it...don't these use ATF for lubrication? Autos can and do run hotter (esp with high stall), so wouldn't worry about the fluid breaking down and since they're manuals, doubt it's anything to be too worried about.
Be curious what the diff temp runs, anybody know?
