From a bad past experience I don't let the water temp get above about 210. The transmission gauge depends on where the probe is located. If mine were to hit 200 I would stop. I seldom let the pyro get over 1200. These temps are easy to manage with a simple down shift and slow down a little when on a hill.

I was born with nothing and I still have most of it left.
