HEAR IT FROM OUR CUSTOMERS

I put Lucas Transmission Fix, it now has over 350,000 miles.

I own a 1999 GMC Sonoma with 123,000 after owning a couple of weeks it wouldn't down shift going uphill they said it would need the transmission rebuilt, it would cost $5,000, I put Lucas Transmission Fix, it now has over 350,000. Thank you Lucas.

It shifts like new now.

Have a 1954 Hudson with noisy low drive, Lucas [Transmission Fix]stopped it. Big trans so we used two bottles. I also have a 1953 Belair that wouldn’t shift up, only manually. Two bottles of Lucas worked fine. Not sure how it does it but it worked for me and it shifts like new now.

Oil Stabilizer and Transmission Fix Keep ’87 T-Bird Rolling

I had an 87 Ford Tbird with several noise and hesitation problems. Tranny resisted shifting, rod starting to knock and cam tappets wearing out. 154,582 miles and I dropped in oil stabilizer and transmission fix and the car drove smooth and quiet for another 129,759 almost trouble free miles. I say Almost because it was after all an 80's Ford. I now swear by all Lucas products.

This product is hands down a dream come true

I wanted to say wonders about the Lucas Trans Stop Slip. I have a 2006 Monte Carlo, that had a fluid and filter change at 92000. After it began to slip alot, I added this to it and BOOM, no slipping! I currently have 115000 and still strong, I will often get a minor slip but am going to add another bottle, regardless this product is hands down a dream come true.

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!
