Review: Solid product (buy extra hose) - Installed it recently, seems to be working well, it came with a very short hose, though, so I had to buy an extra hose in my case to work with Altima 2017.

And it did what it made for, it reduces the transmission temperature by about 20 degrees. Recommended for crossovers with small cooler like the rav4, it will shift better and hopefully last longer. ## Frequently Bought Together - Hayden Automotive 678 Universal Rapid-Cool 9.5” x 11” Add-On Transmission Cooler – Not for Direct Replacement of the OE Cooler - Hayden Automotive 253 Metal Mounting Bracket Kit - Magnefine 3/8" Magnetic Inline Transmission/Power Steering Filter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/256678226-678-rapid-cool-plate-and-fin-transmission-cooler](https://www.desertcart.com.ar/products/256678226-678-rapid-cool-plate-and-fin-transmission-cooler) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-08-17*
