The big question is, how long to you plan on keeping the car ? I would go
to an independent garage and see what they charge. $ 600 sounds like a * lot
* of money to
change out some fluids. Consider using a Turkey baster, or syringe, and
draw out some suspect fluid, and squirt it
on some clean white paper. No dirt = probably OK,
dirty = change it ! I'd also consider what type of fluids are used. GM
approved would be bare minimum for me.
Synthetic trans fluid will add years to transmission life.
Silicone brake fluid, not a simple change out, as old fluid has to be
removed, system flushed totally, as the two fluids are incompatible. Will
add years to life of brake components, and is a great way to go if you store
Since it sells well, Synthetic oil is recommended by GM
I'd go a step further, and use racing grade fluids when
ever possible. I do my own work, and the cost is limited to product.
