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. Read more

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. Read more

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! Read more

Forget every other transmission product and just buy this. I buy and sell used cars and this has always worked. Pay a little more; you won't be sorry. This is what you want ! Read more

My 2012 ford focus had a shifting problem warning message would pop up to safely stop the vehicle that transmission was overheating. And I would pull over and shut it off and wait 30 minutes and try to make it home. It got more worse and the reverse stop working. After I used this product instead of pulling over several times during a trip it would require only one time to pull over and thereafter it didn't overheat anymore and now it never happened again and drives without any problem and the focus has over 200k miles and still drives without any shifting and overheating problems. It worked for me and the least I can do is write a review that it did work. I have purchased hundreds of items from Amazon and never bother to write any reviews but for this one I must. There is a good chance this might work for you too Read more

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. Read more
