If both this is a start. I bought this cuz my 9 f250 wasn't shifting right in highway when towing a boat installing this I have no problem going 80 miles an hour if I want **Q: will this work on my infiniti q50?** A: Although these kits are generic and very versatile, I strongly suggest that you check with Hayden Automotive tech support about your particular application. Also be aware that not all components/hardware necessary to adapt the tranny cooler to your vehicle may not be included in this kit - or any other brand kit for that matter - so some "shade-tree mechanic" ingenuity may be required. BTW - this Hayden Automotive cooler works well on my Avalanche and I have not had an issue with transmission oil temp since install. **Q: Is this item returnable in case it doesnt work?** A: The only way it wont work is if it's plugged or installed incorrectly. Otherwise how can you determine if it doesn't work? You would need to document temperature before and after installation **Q: Can this replace my oem trans cooler?** A: I will bypass the oem cooler bc, I live in the Az. n don't need to heat up the atf even more. The instructions say to run them both in a series. Find some fittings First... to connect to the trans. cooler lines...size diameter and fine thread n barbed n then to the Hayden cooler hose. I bought a second fitting from Hayden like one that came with it It's still too hot here to install, and deal with more aggravation if things don't work out. good luck ## Frequently Bought Together - Hayden Automotive 405 Ultra-Cool Tube and Fin Transmission Cooler - Derale 25793 Fluid Control Thermostat Bracket Kit,Silver - Derale 13011 Fluid Control Thermostat Kit,Silver --- ## 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/1279803-hayden-automotive-405-ultra-cool-tube-and-fin-transmission-cooler](https://www.desertcart.hr/products/1279803-hayden-automotive-405-ultra-cool-tube-and-fin-transmission-cooler) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-17*
