Hot Shot's Secret - HSSTSE32Z Shift Restore Automatic Transmission Additive 32 Fluid Ounce Bottle

fixed hard shifting in transmission

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!

Product works as advertised. Have a 2013 Chrysler Town and Country with 128,000 miles and the transmission was exhibiting harsh downshifts and pump noise. Pumped out about 16 oz of ATF+4 fluid and replaced with Hot Shots Secret Shift Restore, started engine and let fluid circulate in the transmission while in neutral. Next day, the transmission was shifting smooth with no harsh downshifts and the pump noise was significantly reduced.

Will use again

So far so good …. Drove car after pouring entire bottle into 2006 Altima that was shifting hard and irregular. After approximately 15 miles of driving vehicle started to shift better and has continued to do so. So far very happy with product.

Use on a service 4t65e rebuilt in 2020 11quarts and this additive no issue before or after

Didnt dix the problem 100 percent but made an improvement

The products at Walmart are universally scams. I have tried enough of them.This one was used by working truck drivers and I planned to use it on a recently-acquired diesel towing rig.Owners of older gasoline automobiles have used this product successfully on vehicles decades older than mine.I was surprised by a shifting problem on my wife's Subaru Outback. The transmission of 1997 had been rebuilt at about 200,000 miles but survived to 450,000 miles through diligent changes to the ATF.Modern synthetic ATF is amazing, but the recent slippage at heavy throttle when the transmission downshifts from 4th to 3rd could be due to wear or to a sticky actuator.This is a "Hail Mary" to avoid another rebuild on a vehicle going toward 500,000 miles.Since this product may need 500 miles to work, I will update this with the results.
