Elias Casseres uses Lucas Transmission Fix in 1992 Ford Explorer

My automatic transmission was noisy and slipping badly in drive and in reverse -- an "expert" wanted $2,000 to rebuild it. He told me not to drive too far because it was surely going to leave me stranded. A body-shop-owner friend of mine told me about Lucas Transmission fix. We added two bottles to my existing oil. Nothing seem to happen until I had driven about 60 miles in three days, then all slipping and noise stopped. My transmission has been running smoothly now for over 2,000 miles. Great product! I have been recommending it to everyone! This is the first testimonial I have ever written!
