On the changing of transmission fluid are you just changing the fluid or getting a flush fluid change ?

What's the recommendation for front shocks ? Has the Z95 suspension.

I've run several GM automatics over 200k miles with filter and refills at normal service intervals. Usually around 50k miles. Get the pan off, see what's in there, clean really well.

Does having the transmission flushed instead of just fluid changed void my extended warranty?
