I'm thinking of putting one of these on the Silverado. Anyone had any experience with the concept of
increasing the oil supply to keep it cooler?

Followup to my last ...

I assume your Silverado has a transmission fluid temp gauge as well as
an engine temp gauge. My Ford F-250 Super Duty does, I know. If I were
noticing higher than normal transmission temps while towing I'd be more
inclined to add an axillary transmission fluid cooler rather than just
increase the capacity of the transmission pan.

If I am not mistaken your truck has the Allison transmission. From what
I've heard, it is a superb transmission for towing ... probably the best
thing GM has going for it in their trucks. Unless it's getting hotter
than normal, I'd leave it alone. Just my humble opinion.

Appreciated. It is the Allison. The book says 200F should be the max, but I've approached that
several times just on I-95 - during stop and go traffic. But I've also read that 235 to 260 isn't
unreasonable. I'll look into an auxiliary cooler, if they make one. The bigger pan increases
capacity by 5 quarts. A friend just installed one.
