HEAR IT FROM OUR CUSTOMERS

IMMEDIATELY the leak was stopped and never leaked a drop for the next 15 years we owned the car.

This story goes about 20 years ago. I was on a vacation with family and we were driving our 1990 Olds 88 (FWD). We had gotten to our destination and the CV axle seal on the driver side had completely failed and leaked out quite a few quarts of transmission fluid. Having no tools or place to fix it close I decided to try a bottle of Lucas Transmission Fix. IMMEDIATELY the leak was stopped and never leaked a drop for the next 15 years we owned the car. That was my first of many great experiences with the Lucas family of products.

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

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!!

I’m definitely a life long Lucas Oil customer now

A couple months ago my 2011 Malibu started having transmission issues. My transmission was slipping and it was slipping really bad, I went to my local AutoZone and picked up a thing of Lucas Transmission Fix fluid. I drained some of the transmission fluid and replaced it with the Transmission Fix fluid. After I replaced the fluid I never ended up having any issues with transmission slipping. I’m definitely a life long Lucas Oil customer now.
