James R. Mock uses Lucas Transmission Fix in 1991 Jeep Cherokee 4.0 with 224,000 miles

Just wanted to say thank you for making such wonderful products... I have a 91 Jeep Cherokee that was about to see its final days due to an overworked transmission... but, as a last ditched effort to keep it out of the junkyard, tried your Transmission Fix, with some new fluid... LIKE THERE WAS NEVER A PROBLEM!!!! I don't know what you put in that stuff, but I am glad you do... I’m a single father of two with a tight budget and a new car was pretty much out of the question. This was over 15,000 miles ago, and no problems at all with the transmission... since then I started using the Oil Stabilizer with my oil changes (smoother running engine, excellent pressure), Gear Oil in the differentials, and the fuel injector cleaner (fuel economy is UP).... all I have to say is... THANK YOU!!! I was never the type of person to expect a “miracle in a bottle” until I started using your products. Now I have a vehicle that most people wouldn't step inside due to the age and mileage, but once I tell them how it runs and why..... a few more customers coming your way!!!!
