I've had very good luck with it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very good manual transmission fluid *by on Reviewed in the United States March 26, 2019* Really like this 75w80 GL-4 MTF from Redline. Works better in my Honda/Acura than Torco MTF. The Torco fluid is really good stuff (I think better) but I picked up a vibration out of 2nd gear, perhaps it was just too slick for the differential or other MT components. This Redline 75w80 GL-4 MTF is of a lower viscosity than the Torco and seems pretty comparable (only in viscosity) to the Honda HG MTF which sounded horrible in my car and wasn't very smooth. My service manual originally recommended 10w-30 motor oil for the MT but then Honda came out with the MTF HG stuff which I tried and immediately switched it out. This Redline is really good stuff and is in the high quality category of Torco, Motul, Mobile One, Amsoil. It's really good, but generally there are certain lubricants that will work better in your car or motorcycle than others. You just have to try them out and unfortunately that can get pretty expensive, since this gallon option was basically $15.60 a quart. Do the research and limit your selections. Since the manual recommends 30k transmission oil changes, this long interval would justify the higher price per quart. ### ⭐⭐⭐⭐⭐ Great fluid *by on Reviewed in the United States October 12, 2025* This Red Line manual transmission fluid makes your transmission shift smooth as butter. ### ⭐⭐⭐⭐⭐ Cured serious shifting issues in my Mazdaspeed3 *by on Reviewed in the United States February 18, 2018* (PLEASE NOTE: old oil shown in photo is the old genuine Mazda fluid! It is NOT used Redline oil.) I used it in my 2010 Mazdaspeed3 with around 75,000 original miles. I changed it myself, shops in the area didn't want to bother with it. The original trans oil had never been changed (quite simply because, Mazda claims the original factory fluid is a "lifetime" fluid, which it is obviously NOT), and came out of the car looking dark as cocacola, and thick as (real) maple syrup. Whereas this new liquid is transparent, with the slightest hint of red, and flows quite a bit easier than the old, nasty black fluid. Before I changed it, I was having serious issues getting stuck shifting into 1st and 2nd (the shifter often wouldn't want to move all the way into gear). It was so bad that I was considering getting rid of the car. But this new oil fixed it 100%. With the old oil I also had an issue with 2nd gear going in with a crunch (worn synchro probably?), this oil didn't completely eliminate that crunch but it reduced it a lot, and now it goes away completely when the car is fully warmed up. I still can't believe Mazda doesn't have a service interval for changing the transmission fluid in the speed3. This fluid absolutely needs to be changed.As for how to change it in the Mazdaspeed3: https://www.youtube.com/watch?v=yWMk_Q1pE8cTip: If you can manage to find a funnel long enough, or extend the one you have, then you won't need to remove the airbox. I extended mine with a plastic water hose. ## Frequently Bought Together - Red Line 50205 SAE 75W80 API GL-4 Manual Transmission and Transaxle Lubricant (MTL) Car Gear Oil - 1 Gallon - Slippery Pete Fluid Pump for Gallon Bottles and Wide Mouth Quart Bottles (Not for Standard Quart Bottles) - Transfer Gear Oil, Transmission and Differential Fluid, Antifreeze with This 30cc Hand Pump - Red Line 57905 75W90 GL-5 Synthetic Gear Oil for Hypoid Limited Slip Differentials - 1 Gallon --- ## 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.be/products/15967055-50205-sae-75w80-api-gl-4-manual-transmission-and-transaxle](https://www.desertcart.be/products/15967055-50205-sae-75w80-api-gl-4-manual-transmission-and-transaxle) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-17*
