Terrible product.
Cooler lines blew out one day after install. As I am writing this July 2026 this cooler has now blown out between the plate and fin assembly. May have wrecked my transmission, dangerous and a fire hazard. Avoid this cooler

Good cooler for cheap
Get different hoses! But it's functional and keeps the temps under 200. Used on my 09 Tahoe

Overall good just cheap hose
Almost really good. It comes with enough hardware and fitting that you’ll need. Just don’t use the hose provided. It busted on me only after 2 hours of driving and had me on the side of the interstate. Replaced with some better stuff. Only reason I’m giving it 4 stars.

Over 1 Year Review GREAT!
Used it on a 2020 Chevy Express 3500 6.0 in my opinion a mandatory upgrade for the van even if lightly loaded. Went from burning trans fluid with very undersized stock trans cooler on a 6L90 to 140-160 degrees. In stop and go traffic on a hot day 90+ with A/C on, max temp. Was 185F trans fluid.
