It prevents leaks, smooths erratic shifting, and extends transmission life, compatible with all major ATF types except CVT and dual-clutch systems. ## Description As your vehicle gets older it demands more from the transmission fluid, which often causes the fluid to shear. When the transmission fluid begins to degrade, oxidation occurs, which leads to rough shifting, slipping and increased temperature. As a result of the increased temperature, the rubber seals and gaskets inside the transmission will begin to harden and may create leaks. Slick 50® Recharged High Mileage Automatic Transmission Treatment is specially formulated with additional additives for vehicles over 75,000 miles to restore and protect your vehicle's performance. Slick 50® Recharged Automatic Transmission Treatment helps to extend your vehicle’s transmission life.NOTE: Use only per label directions.DIRECTIONS: Always check and follow owner manual’s automatic transmission fluid specifications, compatibilities, and procedures.Keep product at room temperature (above 55°F).Engine should be “warm” and running before and during application.SLICK 50® Recharged High Mileage Automatic Transmission Treatment has a “dripless” gel consistency. Place a funnel into the transmission dipstick tube for easier filling. NOTE: Application time may take-up to 10 minutes.Add only one container of SLICK 50® Recharged High Mileage Transmission Treatment to normal size automatic transmissions. Do not overfill. After adding treatment, continue to maintain your vehicle’s automatic transmission fluid according to manufacturer’s instructions.Store and transport in a closed and upright position.FOR BEST RESULTS, USE AT LEAST EVERY 30,000 MILES.SAFE FOR USE IN:Passenger cars, trucks and SUVsCommercial vehiclesOff-road vehiclesMobile equipmentAll automatic transmission fluids including Mercon and Dexron VI.NOT SAFE FOR USE IN:Continuously Variable TransmissionsDual-clutch transmissions Review: Unfortunately I never got to use this in my car's gearbox, as it died before I could apply. I can say however that I've been using Slick 50 products for many years and the quality and results in achieving smooth engine and gearbox operation over a sustained period of time is really impressive.

I can say however that I've been using Slick 50 products for many years and the quality and results in achieving smooth engine and gearbox operation over a sustained period of time is really impressive. ### ⭐ Review *by A***R on 3 August 2024* It didn't work at all. ### ⭐⭐⭐⭐⭐ Review *by M***K on 12 November 2019* I added Slick 50 oil treatment at my last oil change (2001 Suburban 1500, 217k miles), and the difference in performance was so good (immediately quieted noisy valve lifters, noticeably smoother idling/running), I'll now be adding it with every oil change. So when I decided to DIY a trans fluid change (with removal of bottom pan and change of internal filter), I figured I'd give their transmission product a try as well. This trans (GM 4L60E) has always been a very solid performer, but the shift from 1st to 2nd gear is a little on the hard side ... I've adjusted for it over the years by just backing off the gas a little as the engine reaches shift RPM for that gear. After I put this stuff in, the transition from 1st to 2nd got noticeably smoother, without me having to do my little "easing off the gas" trick. I wouldn't call it some kind of "miracle" ... just a good product that gives older engines/transmissions a little help ... well worth the minor cost it adds to your oil and trans fluid changes. ## Frequently Bought Together - Slick 50 41806015 Recharged High Mileage Automatic Transmission and Engine Treatment, 15-Ounce , black - Slick 50 750002 Recharged High Mileage Engine Treatment, 15-Ounce - Slick 50 Original Classic Engine Treatment with Cerflon, Ceramic Protection Against Friction and Heat, 32 fl. oz, 1 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.vu/products/302507502-slick-50-41806015-recharged-high-mileage-transmission-and-engine-treatment](https://www.desertcart.vu/products/302507502-slick-50-41806015-recharged-high-mileage-transmission-and-engine-treatment) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-12*
