(Manual transmission)** A: It's in my 2014 CX-5 which requires 75W-80. Works better than Mazda MTF. **Q: What kind of improvement will I see using this over factory in an mt82 in a mustang?** A: Not much, it runs a tad smoother when at temp but the notorious 3rd gear issue is still present, I noticed 5th would also scratch when it got really really cold. I'm thinking about switching to ATF like most others have in accordance with Ford's specs. **Q: I have a bmw 89 325IS and i need 80w gl-4 which one is the one i need to get?** A: If you have a manual transmission then you are looking at the correct one which is part number 50204 **Q: Is this safe to use in my 1980 Mercedes Benz 240D?** A: Did a search on Pelican Parts for your 240D and it recommends this fluid for your manual transmission. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by E***Y on November 6, 2023* ### ⭐⭐⭐⭐⭐ Review *by M***E on July 12, 2012* ### ⭐⭐⭐⭐⭐ Review *by C***. on March 24, 2026* ## Frequently Bought Together - Red Line 50204 SAE 75W80 API GL-4 Manual Transmission and Transaxle Lubricant (MTL) Car Gear Oil - 1 Quart - Slippery Pete - Fluid Pump for Standard Quart Bottles - 8cc per Pump Stroke and 3rd Hand Adapter, Transfer Gear Oil, Transmission and Differential Fluid (28mm) - Red Line 50204 SAE 75W80 API GL-4 Manual Transmission and Transaxle Lubricant (MTL) Car Gear Oil - 1 Quart (2 Pack) --- ## 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.co.uk/products/2018135-50204-sae-75w80-api-gl-4-manual-transmission-and-transaxle](https://www.desertcart.co.uk/products/2018135-50204-sae-75w80-api-gl-4-manual-transmission-and-transaxle) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-14*
