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!

Uses Lucas Transmission Fix

I was traveling thru California on my family vacation, when my transmission suddenly started shifting hard in low gears and slipping. All that went thru my mind at that moment was great , this is going to ruin my plans to take my kids to Disneyland . It then crossed my mind , how am I going to get my vehicle home 600 miles away. I stoped into a pepboys (where i also work at back home), and I purcased a lucas transmission additive . I removed a quart of transmission fluid and added your additive . Since that moment till a month later (today) , I have had smooth sailing with my vehicle. I know this additive is not my permanent solution to all my transmission needs, but I want to thank you for making a good product. I really feel that your product helped me out of a jam that could of ruined my family's whole vacation. Now at work when my customers request my advise on what additives I recommend, its going to be lucas, because now I am really a believer. Since I work in retail , and I know sometimes all you ever hear about is complaints, I wanted to let you know you produce a good product and you should be proud of that product. thanks again

Thanks for what you do!

I purchased a bottle of Lucas Oil Transmission Fix yesterday and put it in my 1981 Corvette collector car I recently purchased at a Mecum auction in Fort Worth. The car has the TH350C automatic with the locking torque converter. The car is all original right down to the last nut and bolt and had spent its entire life indoors when not being driven in perfect weather. I’ve driven it about 500 miles since I purchased it and noticed recently that when in park and idling the transmission whined a bit, kind of like a needle bearing starting to show some wear. I started researching your product because of the Lucas reputation and bought the Transmission Fix product and added it yesterday afternoon and immediately the whine went away but as I drove it I realized that was just the tip of the iceberg. It shifts so smoothly that it almost feels like it has a CVT transmission in it. When the locking torque converter kicks in that is a lot smoother as well. When I shifted it from park to either reverse or drive the first few times I thought the shift linkage had broken it moved so smoothly. The motor seems to not be under near as much stress idling in park or going down the road and a lot of just overall noise is gone from the car. It was one of those kind of deals where I didn’t realize the noise was there until it was gone. Thanks for what you do!

Lo and behold the leak stopped almost immediately.

My daughters Highlander 2001 over 100k miles was leaking badly transmission oil. Took it to mechanic and cost to do work was pretty high. We decided to hold of the job and the mechanic suggested we use this product meanwhile. We did, and lo and behold the leak stopped almost immediately and now we can park it inside the carport. We couldn't do this before because of the big splash of the leak. Thank you Lucas stop leak...It Works!!
