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

Trans renewed.
Had an old Supra that wouldn’t reverse. Seldom driven. About two weeks after using the product, reverse began working again. Trans worked well until the head gasket blew and I sold it.

Slick 50 strikes again ...
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. ... show more

Transmission shop recommended
We purchased a 1985 Dodge Ram 150 half ton truck for our son to learn to drive. It has a fresh V8 engine, a 318, but the old automatic transmission. The transmission was slow and rough shifting, plus it was hard to pull the shift lever from park to drive. First gear was noisy. Cold weather made the problems even worse. Old fluid had been drained from the pan, but old fluid in the torque converter remained. The problems did not change. I remembered a mechanic at a transmission repair shop suggested this Slick 50 product to my Dad, so I thought I'd give it a try. This product works! We have driven 600 miles since adding the product, still as good as day 1. Shifts are smooth and fast. The gear shift lever moves into position far easier. First gear is much quieter. If you are looking for a transmission re-conditioner, I recommend this one highly! I think so much of this additive that I bought a second bottle to give to our son's high school friend whose transmission is having a similar problem. ... show more

I worked great in our Chevrolet!
I added Slick 50 Recharged to a 2004 Malibu Maxx with 180,000 miles. The transmission was beginning to "shudder" and I was told a rebuild was in my future. My friend said to try this first and after adding the entire contents to the transmission, it improved the shifting and ride immensely. My wife says she no longer feels the same shudder that was present before application. Momma is happy, therefore, I am happy! ... show more
