Transmission Cooler Questions
Hello All,
Hope you guys are doing well today and had a good weekend! This might sound like a dumb question, but I've just been thinking about it and am curious about it. So I have an SS1LE with the A10, and since I do plan to add more power to it eventually, I plan to change out the stock transmission cooler to the ZL1 A10 transmission cooler. I'm wondering if there would be any type of cooling benefit to add the SS transmission cooler in-line somewhere else for the transmission cooling system, say from the transmission to the e-diff, or from the e-diff return to the transmission? Any thoughts on this? |

It seems like there's building evidence that controlling engine oil cooling has a strong impact on the entire cooling system. As you might already know, all of the powertrain cooling, except the supercharger (in ZL1s - duh), pass through the radiator in some fashion. As a consequence - there is a huge load on the engine radiator, with one tank having the engine oil cooler and the other side containing the tranny/differential. Evidence is showing supplementing/replacing/divorcing the engine oil cooler from the primary radiator circuit improves track performance for ALL. One method replaced the supercharger aux. cooler with an engine oil cooler and significant coolant and engine oil temperature improvements were found. Another found considerable improvements in eliminating the aux. radiator (right cheek) with a dedicated engine oil cooler. I believe BOTH eventually divorced engine oil from the OEM engine oil cooler, but BOTH methods showed demonstrably improved TOTAL powertrain cooling, including tranny. Not to take away from your idea at all. BUT - because you're wanted to track the car, perhaps the engine oil cooler circuit is best addressed. I will freely admit I haven't tracked my car, and may never, but I HAVE noticed that I can heat the oil up under certain driving circumstances I wouldn't think would matter (and it's repeatable, so I know it's a thing). The single thing I worry about, is foul weather driving, and driving with engine/tranny oil too cold. I wonder if GM designed the cooling as it is for COLD weather, too. I'm sure hardly anyone will beat on the car in the freezing weather, but I wondering if that's part of the design architecture that we got from them. Let us know what you come up with!

![]() My thought about adding the ZL1 cooler was that it's pretty OEM already and it's an easy swap, so that's why I was looking at that avenue. I plan to address the oil cooling as well by adding the C&R coolers up front, as those seem like they've been proven to actually work. |

I know there's a point of diminishing returns, too, as far as core design goes. Sometimes too thick starts restricting flow to the cores behind it and I've often wondered if my thicker HE helps or hurts, but it's face isn't any bigger than stock, so I'm crossing my fingers at least that's okay. Who knows?... LOL.
