whats the normal trans temp and what would be high, the norm temp for coolant and high and then egts temp whats normal and high

 

Tranny should run between 60 and 80 deg above ambient air. Anything above 200 begins to toll on transmission life.

Water? I don't monitor it so I can't say exactly. The PSD has such an efficient cooling system that I have not worried about it. If I had to guess, I would say the 210 - 220 would be a good operating range.

EGTs. They need to be measured pre-turbo. There is no normal because depending on throttle position, grade, weight, altitude and numerous other factors, EGTs can range from 300 to 1200 deg. I would expect to see while driving down a flat stretch of highway, empty with no headwind and just cruising, about 700 deg. Pre-turbo temps should be kept under 1250 deg, it can be exceeded for short power bursts but prolonged high temps will stress pistons and cause them to eventually separate.
