C6 cooler line, tap case larger?

Any benefit to enlarging the case tapped holes to run larger lines?

Can anyone explain the hydraulic circuit and how/where fluid gets from the converter to the cooler? What meters that flow and can/should it be altered?

This is going in a big heavy, large tired truck with a fair amount of power. That trans will need all the cooling I can toss at it.

When I ran a C6, n my pulling truck, it was 720hp and the truck weighed 6200lbs. I just installed -6an adapters in the case and ran -6 line. You don't have to drill and tap the case.

I have the same thing on my car with a big B&M cooler up front. Zero issues.

The amount of fluid going through the cooling line is controlled by whatever the by-pass of the pressure regulator relieves. After going to and back from a cooler it re-enters the transmission as the lubricating fluid throughout, The cooler that fluid gets; the better.

That is usually OK for any drag racing or regular street use.  Road racing or oval track needs a separate set of cooler lines from the pan to a pump through a cooler and re-enter the transmission above the planetary gear-sets.

Thanks Randy, I assume the pressure is set in the pump or is it VB function?

Is there a link anywhere I can look at the fluid path? I assume the pump pulls from the pan and that pressurizes the hydraulic circuit for transmission function, the relief of that goes to the cooler and back as lubrication oil. Where does the converter supply/relief come in to play? Does it charge off of the cooler circuit of from the control circuit? Any recommendation on external pumps for the budget minded if there is such a thing, Thank you.
