L.W. Cartnett uses Lucas Transmission Fix in 2000 Pontiac

Dear Sir,

I recently tried Lucas Transmission Fix in my 2000 Pontiac, and am very pleased with the results. In 2004 I bought a 2000 Pontiac with 50,000 miles on it. Some time later I discovered that the transmission was changing rough. I got worse and I took it to a specialist. He checked the transmission and informed me that it needed a rebuild. The estimated was over one thousand dollars. I am on social security and unable to come up with that much money. I also could not trade for the same reason. I had to look for another alternative.

I went to a local Autozone Parts Store. The clerk said he had many customers who liked Lucas Transmission FIx. I decided to try it. I installed the product in my car. After a few days my transmission began to change smoothly and has not given any more problems. I now have 70,000 miles on my Pontiac and the transmission still works very fine. It is good to find a product that actualy works as it is advertised to. I am pleased with Lucas Transmission Fix. It saved me over one thousand dollars. I have recommended it to many other people. I have yet to have anyone say it has failed to do what it is suppose to. Thanks for a product that does work as advertised.
