I never seen that kind of bill for 30k.
I would call ALL the GM dealer's in your area to see what they charge.
I think you should ask them to break it down to
1.fluid cost.
2.labor cost
2b.flate rate hours involved.
2ba.parts involved and cost.
3.then tell them no wonder people go to monkey Fing wrench lube,
what ever the hell it's called.
4.Your too close to the island of Cailfornia.
Move to the east coast. way cheaper>
