As far a transmission fluid change, what they did with yours is one way to do it but another is a machine that is tied into the inlet and outlet for transmission fluid. Old fluid is pushed out and the new stuff put in. As the engine is running during this procedure, pretty much all the fluid is removed and replaced.





I know nothing about copper getting into the brake system.


I buy Costco gas 99% of the time. It's top tier. I was told that since the injection of gas is into the cylinder itself, instead of on top of the valve when it's opening, the top tier formula is not cleaning the tops of the valves.

This is interesting and a squirrel hole I found when looking for information. A Pilot owner's discovery of the tool.

Why is there copper in my brake fluid?

I asked Google.
The copper alloy used to coat the inside of brake lines is where the copper content of brake fluid comes from. The brake fluid dissolves it from the interior of the brake lines and suspends it in the fluid.

All sounds good Patty. Did you notice a difference driving it after the repairs?

It seems a little smoother but that could be my imagination.

That Subaru was surprisingly decent. No complaints since I never needed to accelerate quickly.

I wonder if that is why stainless brake lines are desirable to some. No corrosion of any kind.

A better question - so what if there is a trace of copper in your brake fluid?

^It sounds like a bad thing because the interior of the brake lines is dissolving.
