Shifts a heck of lot quieter and finding neutral isn't an issue thus far. Think I like it better than amsoil's trans fluid. ## Frequently Bought Together - Red Line 42804 Full Synthetic Gear Oil, V-Twin Transmission Oil with Shockproof - 1 Quart - Red Line 42904 V-Twin Primary Case Oil, for use with UTVs, ATVs and Sportbikes - 1 Quart - K&N Motorcycle Oil Filter: High Performance, Premium, Designed to be used with Synthetic or Conventional Oils: Fits Select Harely Davidson Motorcycles, KN-171B --- ## 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.vn/products/3981526-42804-full-synthetic-gear-oil-v-twin-transmission-oil-shockproof](https://www.desertcart.vn/products/3981526-42804-full-synthetic-gear-oil-v-twin-transmission-oil-shockproof) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-04*
