How does this differ? Would i need to purchase this also?** A: I Depends. What are you using your vehicle for? Day to day running around? If so then probably not. BUT if your using your vehicle for towing is the new radiator with the built in trans cooler meant for towing or extrema environments like Off roading? If you are just tooling around town and not doing much with your vehicle then a stock replacement radiator will be find BUT if you are towing/off roading/ racing then I would recommend it. I tow a jet boat with my vehicle and noticed that temps would go up when towing so I put this in and plugged off my old internal trans cooler and temps are great now. Hope this helps **Q: IS this an add on or des it replace the stock one?** A: This can be either a supplement to your current cooler which in many cases is integrated into your radiator, or a supplemental cooler if you have none.I have a 2006 Nissan Xterra which along with several other models, is prone to a failure of the stock, shared radiator unit. When it fails, radiator coolant enters the transmission contaminating it and causing a catastrophic failure. I intend to bypass and cap the stock cooler where the lines come from the bottom of the radiator and use this unit for 100% of the transmission cooling. This is a small price to pay for eliminating the risk of cross contamination and a costly tranny replacement. ## Frequently Bought Together - Hayden Aluminum Automotive 403 Ultra-Cool Tube and Fin Transmission Cooler - Hayden Automotive 106 Transmission Oil Cooler Hose 3/8-IN Diameter x 4.5-FT Length - Upgraded CVT Transmission Oil Cooler Compatible with Nissan 2007-2012 Sentra / 2011-2014 Juke / 2008-2018 Rogue / 2012-2018 Versa Sedan 21606-1XF0A 4 Ports by 3mirrors --- ## 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/208869187-hayden-automotive-403-ultra-cool-tube-and-fin-transmission-cooler](https://www.desertcart.hr/products/208869187-hayden-automotive-403-ultra-cool-tube-and-fin-transmission-cooler) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-08*
