Same now on auto transmissions, no change. Fluid always looks new, no combustion, done.
I also dont flush my brake lines. Or flush coolants.
Change the oil, lube drivetrain, that is all. Everything else is really not needed anymore in my opinion. Waste of time and money in most instances.
Your mileage may vary, and just what I do. 11 years/165k in my latest truck, owned since new.
If you changed the fluid out early in its life, thus removing break in grit, thats exactly why the fluid still looks new later in life. You cant see the viscosity loss and additive depletion, so I'm not sure the fluid coming out "looking new" is a good reason to stop maintaining the fluids on a vehicle.
