Also don’t like mounting to the condenser coil, made my own brackets. **Q: I have a '04 chevy trailblazer 4.2 i6 4wd with factory trans cooler. looking to upgrade to pull travel trailer. is there anything else i need?** A: I would leave the factory trans cooler in place and add the Hayden trans cooler in line if at all possible, especially if the factory cooler is a plate and fin cooler. It will give you that much more extra cooling. **Q: Did you bypass stock trans cooler on 4runner?** A: I did it on a Nissan Rogue s , am using both now , but planning on by pass it when I hit the 100 k miles ‘cause usual failure of stock oil cooler and don’t want to get any water in tranny. Hope it helps . **Q: Will the provided adapter fitting thread into my radiator on my 2003 gmc sierra 4.8?** A: It comes with a fitting, I’m not sure if it’s universal. I spliced mine into the existing hoses deleting the OEM cooler. ## Frequently Bought Together - Hayden 679 Universal 11” Rapid-Cool Add-On Transmission Cooler to Enhance Cooling (not for direct replacement of the factory unit) - Hayden Automotive 253 Metal Mounting Bracket Kit - Hayden Automotive 106 Transmission Oil Cooler Hose 3/8-IN Diameter x 4.5-FT Length --- ## 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.hr/products/180949332-hayden-automotive-679-rapid-cool-plate-and-fin-transmission-cooler](https://www.desertcart.hr/products/180949332-hayden-automotive-679-rapid-cool-plate-and-fin-transmission-cooler) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-25*
