Robert Worley uses Lucas Transmission Fix in Ford

I just want to say that your trany additive has so far saved my company from going under last year I bought a Ford F150 not being a Ford man myself was a little concerned about the milege. After a fall out with my previous employer I decided to go off on my own with a Ford for a work truck( how's that for stress)well I got the licence to work and driving home from city hall my truck shifted with somewhat of a clunk and just got worse from then on. I'm the kind of guy that thinks additives create more of a problem then good and hesitated hard I had no money and a truck on the way out. My dad said to try your product he is the same way fix it now and dont add to the problem. Well about a week after adding the clunk was gone along with the stress the Ford has 389,000 miles on it and was well maintained since I have added it. I have drove the truck 4 months with no clunk the company has started generating money and all I have to say is god bless. Couldn't have done it without the Ford, and the Ford coulnd't have done it without Lucas, Thanks!
