HEAR IT FROM OUR CUSTOMERS

12,000 miles later, the car shifts and operates better than when I purchased it.

About a year ago, I got a transmission flush in my 2005 Mercury Sable. However, upon doing so, it became apparent that the vehicle had never had the ATF changed in its 145,000 mile lifetime. So, all the clutch material that had basically allowed the tranny to operate normally was gone. The car would not stop bucking and slipping. Someone recommended Lucas Oil Transmission Fix, and so I added copious amounts of it. 12,000 miles later, the car shifts and operates better than when I purchased it. Thanks, Lucas Oil!

Now It Doesn’t Slip At All.

My transmission was slipping in 1st and 2nd gear and would take a minute to catch first when taking off. Now it doesn't slip at all, still takes a second to catch but not nearly as long.

It worked great… Quieter, smoother transmission…

I had a slight slip / grab in my 2003 Astro van trans. It has 145k on it.. I decided not to change the fluid but to add Lucas Transmission Fix product. It worked great... Quieter, smoother transmission... glad I used it.

Added Transmission Fix & now my tachometer works

I recently bought a 2006 Ram 1500. The tachometer didn't work, & the dealer stated they would fix it. They tried. They replaced the old one & the new one didn't work either. They tried on numerous occasions, & finally told me they had to make an appointment with the Manufacturer. The other day, I bought the Transmission Fix, as a preventative measure. Added it, & now my tach works.

There was a NOTICEABLE difference within 10 minutes

My daughter has a 2006 Mercury Milan 6-cylinder. It has 110,000 miles on it and she mentioned to me last week that it sounded like it was shifting weird from 1st to 2nd. I took it for a drive and noticed it was starting to slip just a bit coming out of first (shift flare). I purchased the Lucas Transmission Fix after reading hundreds of 5-Star reviews and after it to the transmission fluid and running it through the gears while the brake was pressed, I took it for a drive. There was a NOTICEABLE difference within 10 minutes of driving it in the city and perhaps 9 or 10 stop lights/stop signs. PLUS, it no longer clunks when shifting from Park to Reverse or from Reverse to Drive or from Drive to Reverse, etc. Love this stuff! Thank you Lucas Oil.
