Shift Restore Transmission Additive, 16 oz | Treats 10 quarts. Helps improve shifting, reduce slipping, and lower transmission heat.

Awesome, stopped slipping in just a few minutes. I highly recommend.

2011 68rfe dually 6.7LDid both transmission filters.Did pan service with AMS oil ATF.Put a banks deep sump pan on it.Put the whole bottle in when serviced.Notice shifting improved seems smoother.Curious to see long term.

I’m So So So happy! I put 5 ounces of shift restore in my F1 transmission, and within 30 miles, all of my shifts were smooth and the grinding between shifts are completely gone. Shifting perfect! The car drives like a brand new vehicle.I was hesitant to try this product, so I reached out to the manufacture and told them that I had a Ferrari with an F1 transmission (basically a manual gearbox with a paddle shift mechanism).It had sat for awhile, and the clutch plates had developed an issue, and I wanted to make sure that this product would not cause any damage to the brass synchros or any other internals of the transmission. I received a quick reply from Logan who reassured me that Shift Restore would have no issues with my application.RESULTS: I couldn’t be happier! The previous owner sold me a lemon with transmission full of antifreeze. It had been sitting in the gearbox for who knows how long (due to failed heat exchanger). The shift restore freed up the rusty clutch plates and got everything working smoothly again. When I would wind up the car and shift at high RPM's the clutch would give me a little trouble shifting gears, but now all the shifts are crisp and smooth. I am truly impressed and very grateful.Thanks a million!

I bought this for my 2007 Honda CR-V, it has a lot of transmission issues that came with the car. It’s loud and always slipping in second gear. I did 3 prior fluid flushes, but it didn’t work. It was easy to put in. I noticed a difference right away. The noise went down a lot and it stopped the shuddering. It seemed to lubricate all the gears with no leakage. The only thing bad I could say is that it didn’t last long. I’ve had it in for about 5,000 miles now and the slipping is back. I know it’s most likely my car, but who is going to be changing their transmission fluid every time this comes back. I think it would definitely work on newer cars without any issues.

Great stuff. Did a drain a fill on my Honda and added the required amount, smoother transmission shifts,big time!I also replaced the filter as well.I also use some of their other products, outstanding company and products.

Used this in my Silverado pickup with 4L60E transmission. Bought with 122,000 miles, changed fluid and filter every 40,000 miles, put this in at 203,000 miles and the trans. actually shifts quicker and firmer now with 232,000 miles than it did at 122,000 miles.

I bought a 2020 Silverado 1500 4x4 for about $15k under wholesale because the seller thought it needed a transmission and did not want to deal with the issue of spending $6k, that is what he was quoted. The transmission would not shift out of first gear. I bought the truck assuming I would be installing a new transmission, the truck had 129K miles on it. I did a pan drop, changed the filter, replaced the lost fluid along with Shift restore. I could not believe it but the truck instantly shifted perfect, i ran it up to 85 mph on it first run and its been perfect since. I bought the truck right even if I did have to put a transmission in it, Shift Restore made my truck deal a steal.

Used this product for my 68RFE transmission and a lot of ppl say it helped there shifting and performance but I could not tell a difference with mine. I did a fresh drain, filled with this hot shot, and fresh transmission oil and filters. Went for a drive and 100 miles later still can’t tell a difference. But I’m hoping this product does clean the transmission components and helps extend the life of the transmission, guess I’ll see on the next transmission drain.

good product, the transmission is far better and smooth.

We own a Ford Fusion V6 3.0L AWD, 2010. First, the PTU failed in November 2022. A week later, the left axle seal failed and in March the right axle seal fail despite we have regiliously changing transmission fluid every 50,000 km. On google, it would seem Ford PTU is notoriously prone to failure. After fixing all the leaks at a reputable shop, I noticed shift up 2/3 is really rough especially when it is cold outside (-5C or below). Reading on amazon, I thought I would give this product a try. Added about 10 Oz and I thought it might take a while, but saw the effect right away. The shift is much smoother and the "kick up" is gone. Drove another 50 km and same positive effect. Very happy and will update after a few months of driving. So far, so good.

Added just 200ml to my transmission and it fixed the problem where my auto transmission was struggling to change from 1st to 2nd.

Noticed results almost immediate on my Range Rover with 140K km . Shifts were sticking 2-3 and now running smoothly. Just feels and shifts better throughout all ranges. Recommend.

Doesn't make any difference in UAE weather.
