Transmission cooler for Tahoe, Yukon, Sierra vehicles, 40K BTU size. Original Canadian made, engraved. Still under warranty. I installed it on my Tahoe for two days and then removed it. Its size is large and it cools the transmission. In the morning, it doesn't reach 50 degrees. It didn't work for me, I need a smaller one. It comes with all its contents: hose clamps, connectors. I bought it from Speed Car website for 600, and the invoice is available. My location is Al-Eis, Madinah region. It's best for those who want to see it in person, or we can ship it to you at your expense. It's best for those who go off-roading, dune bashing, or towing. For regular city driving, a smaller one is sufficient 👍🏻
