Didn't see a forum specifically for transmissions, so I figured I'd just post here where I hang out the most. I've got a C6 that's currently plumbed into an integrated cooler in my radiator. I'm thinking about going with a dedicated tranny cooler & wondered if anyone had any experience with the "Heat Sink" type coolers? I like the look and the form factor, & it looks like they're full flow. Opinions???
It has a built in transmission cooler. I'd use it.
The reason that the transmission coolers inside a radiator are so efficient is that there is engine coolant surrounding the hot ATF. Water is a FAR better means of extracting heat than air is, so even if the transmission cooler is just a loop of tubing inside the cold end tank it will still remove a lot of heat from the ATF. Then send the ATF to an air to oil cooler out front to cool the ATF even more.
