how much should i pay for coolant service, power steering service, transmission service, differential service, brake fluid service, induction system tuneup?

is there anyway u can call our shop?? we will give you an estimate for what u request but can tell u that coolant is good for 100k by the maintenance schedule provided by GM, some other fluids not even mentioned as part of a regular schedule. would like to actually inspect fluids for contamination, discoloration, etc.. see what is NEEDED, not just being sold to u. also using genuine GM fluids would be slightly higher and would be recommended
