I wanted to give you guys a huge thumbs up. I have tried many different products in the past as my being a mechanic, but Lucas… I’ll tell you what it is the best I have ever used. I used some of your Power Steering Stop Leak and trans slip stuff [Lucas Transmission Fix] got me started. Now that is all I run in my mud truck gear oil and differentials. It is what I use in all my sand toys and four wheelers. Crankcase and it has never ran better. My gears are quiet, my wet clutch packs love it. So does everything else that I put it in. Please keep up the good work and I do tell everyone that I highly recommend it, in anything. You guys are great and you make an amazing product. I will forever be using your product.

I have been using your products for over 6 years now and I would just like to say that they are amazing! I own and drive daily a 2002 Chevy Avalanche with 334,215 miles. About three summers ago my transmission started to slip, First thing that came to mind was to put your Transmission Fix in and just like that it went back to new! Other than that I use your Oil Stabilizer on every oil change and am very impressed with the stuff you guys put out! Im currently using your Power Steering Stop Leak and its showing signs of improvement! Other from the Oil Stabilizer my favorite product is your Fuel Treatment, I was having super rough starts and 1 bottle of your magic fixed the issue within a day! I just wanted to take the time to thank you and wish the best for your company and employees. Yours forever

Lucas Transmission Fix works. I was skeptic, I was not convinced it would work. But my mechanic recommend that I give it a try. Stop the rough shifting on my automatic transmission. A product that does says. Lucas makes good additives…

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.

1991 Chevy S10 Blazer, had slippage issues in the transmission and had well over 200k on the clock & putting in a rebuilt transmission even for a tech like me would be worth it, well I put the Lucas Transmission Fix in the transmission drove it for a few days and it literally stopped the transmission slip, this was about 10ish years ago and now the S10 is pushing 300K which another friend has it now, but I have become a avid Lucas Oil Product fan. Thanks Lucas.

My 2004 Dodge Dakota 3.7 automatic was slipping and jerking 35-40 miles mph feel like I was running over the pay attention ribs cut into the edge of the blacktop. Anything above or below the 35-40 mph was fine. I added one bottle of Lucas Transmission Fix and immediately the problem was GONE!! I was a little concerned because it came out of the jug like honey “thick” but it did the trick. Thank You LUCAS OIL!!! You got yourself a lifetime member!!

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.

I have a 1990 Corvette which I have owned 25 years. I replaced 4 transmissions and this time the 4th one started slipping in high gear and I had enough. These are coming straight from GM. I decided to try your Transmission Fix and read works “immediate”. I thought wow, that’s a bold statement. I followed the directions, took the car out and ran it through all the gears. It actually shifts better then ever. Love your PRODUCTS!!!.
