My burb has about 172k miles on it and I am planning on doing a longish road trip with my family this summer, about 2k miles. It rides great, starts instantly after turning over once. My big question is, does anyone know of any parts that tend to go out on these burbs when they get to this mileage? I know the transmissions aren't the strongest, but this burb has not seen much towing. I would hate to be stranded with an angry wife and 4 grouchy little kids. I have a 1996 suburban k1500. 5.3, 4l60e. As far as I know, there has not been any major work done on the engine or transmission. Extras include a throttle body spacer, cold air intake (air raid), corvette shift solenoid, a dvd system with an extra amp, dual cat back flowmaster exhaust. Thoughts?
