I couldn't find the trans cooler on my 2022 Silverado 2.7 with 8 Speed trans. I figured it had to have one to be able to tow from factory 9000 lbs. Turns out there is a liquid cooled one bolted to drivers side of tranny that looks identical to an engine oil cooler (which coincidentally is located right next to it). Liquid cooled oil coolers are obviously are way more efficient than air to oil coolers, however, when that liquid is 210 degrees I’m not sure how much help that is. Hopefully it has been battle tested. Aftermarket air cooler ain't happening since there aren’t any trans cooler lines going to radiator area at all (and I’m not running 15 foot of rubber hose).
