I know this is Class A forum, and I have a class C gasser but since many I'm sure here have owned a C, is it recommended/possible to drive down a hill in 2nd for an extended period without doing damage to the transmission? I'm a new,first time owner.
It depends on what year coach you have. Newer coaches have transmission temperature warning indicators that should tell you if you have a problem. Otherwise you can install a trans temp gauge. Its a good thing to have. Going up a grade heats the engine and the trans. Since the trans fluid runs through your radiator, the engine heat is not helping your trans any when under extreme loads. Under normal driving the engine heat is good for your trans, but pulling a long grade is too much of a good thing.
