Lucas Transmission Fix is the real deal!

Lucas Transmission Fix is the real deal! My transmission delayed shifting out of 1st gear sometimes wouldn’t shift at all. 1994 Dodge 3500 w/ 5.9 Diesel. Three different transmission shops said the transmission needed to be rebuilt. I changed the fluid and filter and added Lucas Transmission Fix and crossed my fingers. After a couple days it started shifting again. That was 4 yrs. ago and still shifts like a new truck.

The transmission has been working perfect for the last 25,000 miles!!!!!!

My 1999 Subaru Legacy Outback started to not go into drive or there was along delay. I heard that this is a problem that many people see with these older Subarus. So I decided to try your Transmission Fix along with changing the transmission fluid with Lucas Semi-Synthetic Transmission Fluid. Well right after the change in fluids the transmission worked better then before and went right into drive. It did however started to have a delay again after a few thousand miles so I did the same fluid change again and the transmission has been working perfect for the last 25,000 miles!!!!!!

Your Products Are Amazing!

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

It shifts amazingly no slips or leaks.

I had a 2001 suburban that would flare between 2nd and 3rd and slipped really bad when warm. I changed fluid and added 1.5 bottles of Lucas [Transmission Fix] and now even leadfooting it it shifts amazingly no slips or leaks, thanks Lucas!!
