i have a 2002 gmc serria 2500hd and just got 35 FT COUGAR FIFTH WHEEL AND NOTICED ON SOME HUGE HILLS THE TEMP GOT TO 221 IS THIS OK IT CAME RIGHT BACK DOWN AFTER HILL??
Rule of thumb especially since I just had all my Differntial and transervice done on my 2002 Chevy 2500 HD yesterday... I bought it last year so I wanted everything gone through and fixed... Just wear and tear... The Trans guy told me the hotter your Transfluid gets the more often you need to get it changed....
