All five of these changes lower the transmission temperature.
The highest trans temperature that I saw was 140°f even though I was driving at 3000rpm, about72 mph.
When the temp dropped to 138°f, it would unlock the torque converter.
The cooler in this SVX is a 15,7/8"total width, and 7,1/2" tall.
It is a Hayden/Imperial #242016 that has six passes.
For a summer car, or a Southern States car its might still be a little on the big side"

I think that is the same Hayden I was looking at. I talked to the technical folks at Summit Racing and asked them which cooler had the lower flow resistance, the Flex-a-lite 4110 or the Hayden 676. They said it was the Flex-a-lite 4110. I think the 4110 also had the smaller footprint. It has less cooling capacity but, as you said, larger cooling capacity may not be a good thing. I could only imagine how cool my tranny would be running in our -18F mornings with a large Hayden cooler.
