Lucas Transmission Fix Stops 2003 Taurus From Slipping

I bought a used 2003 Ford Taurus with 80,000 miles in great shape. When the transmission was cold it shifted into reverse just fine. When it warmed up it slipped considerably when shifting into revese only. There was no problem in all forward gears. I added a bottle of Transmission Fix and it reduced the slipping. I then drained the transmission fluid from the pan, changed the filter and refilled the transmission fluid using another bottle of Transmission Fix. After driving it a few miles and warming up it shifted into reverse just fine and the problem was solved with no further slipping. I was amazed!

1 bottle of transmission fix and the car shifts better

I want to say that your product transmission fix is absolutely incredible. Lexus wants about $7000 for a new trans to correct hard banging sloppy shifting. 1 bottle of transmission fix and the car shifts better than when I bought it new 75000 miles ago. Thank you Lucas Oil for the great product that really 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.

No more drips, transmission runs 20 degrees cooler and it shifts like a new truck again…

My 2011 Ram 1500 has 170,000 miles on it and I noticed a couple of drips of trans fluid in the snow where I park. I picked up some Lucas Oil Transmission Fix and now no more drips also transmission runs 20 degrees cooler and it shifts like a new truck again, smooth baby smooth!! Thank You Lucas Oil!! P.S. I now use your products in my gas and engine now.

Car runs like it never had an issue.

My wife's 2006 Pontiac Grand Prix was having transmission issues (slipping at the peak of 1st into 2nd). After my wife purchased a diagnostic A&R Transmission repair shop told me that the trans was crap and needed to be replaced ASAP! LMAO!! NOT TODAY BUDDY!! I Replaced filter, fluid and used the Lucas Transmission Fix. I used about 28oz to 30oz. Car runs like it never had an issue. Drive it lightly a day or so and you should start to feel the difference.
