How does it hold up?** A: I've been running it for 35,000 miles in my 1996 model GM NV4500 without issue. **Q: Do I pour the entire contents directly in? Are there any special instructions?** A: To get maximum benefit of the Red Line you need to replace all the oil in the transmission. For my car, it took 3.4 quarts so I bought four and filled it up until fluid was level with the bottom of the fill plug. If you go to the Red Line website, they have which transmission oil is correct for your car and the capacity of the transmission so you will know how much you will need. **Q: Is this product non-synthetic gl-3?** A: Synthetic gl -4 oil **Q: Can i use on 1992 chevy camaro rs?** A: I would not. It is supposed to be OEM recommended for my 98 vw Cabrio 5speed. So Put $46 worth in and at0°F I could not shift the car until 30 minutes of idling. second Synchromesh was very fussy at 20deg ## Frequently Bought Together - Red Line 50304 MT-90 75W-90 GL-4 Manual Transmission and Transaxle Lubricant (MTL) - 1 Quart (2 Pack) - Red Line 57904 75W90 GL-5 Synthetic Gear Oil for Hypoid Limited Slip Differentials - 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) --- ## 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.com.ar/products/343633702-50304-mt-90-75w-90-gl-4-manual-transmission-transaxle](https://www.desertcart.com.ar/products/343633702-50304-mt-90-75w-90-gl-4-manual-transmission-transaxle) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-04*
