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!!

ONE bottle and the transmission worked PERFECTLY again.

I own a 2002 Toyota Tundra, the radiator failed and allowed the coolant and transmission fluid to mix. It was immediately apparent that I had a MAJOR transmission problem. Someone suggested your Transmission Fix/Stop Slip product to me. I added ONE bottle and the transmission worked PERFECTLY again. THANK YOU for saving me what I thought was going to either be a very expensive repair bill or having to purchase a new transmission or vehicle. GREAT PRODUCT.

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!

It actually shifts better then ever. Love your PRODUCTS!!!

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!!!.

Within about 20 miles it was driving like a brand new car.

My '02 Chevy Cavalier coupe is definitely one of the nice looking ones still around, except that I noticed some play in the transmission at around 98,000 Miles. Even after a flush and fill with new transmission fluid, I would get hard shifts and a delay in kick down. I put this Lucas Transmission Fix stuff in and within about 20 miles, it was driving like a brand new car, with pillow soft and effortless shifting. I am pushing 120K and its still running better than ever! Awesome stuff!
