Rodny Morris uses Lucas Transmission Fix in 1995 Ford Contour

I borrowed my sons car to go to the store I was shocked at how hard it shifted. it would jerk my head back and squak the tires shifting to second gear. I asked my son about this and he said it's been that way for awhile. I told him there was no way his trans was going to hold up much longer like this and it was going to go out soon. I've heard of Lucas Transmission Fix so I thought what the heck the trans is going out anyways. It worked immediatly!! It has been two weeks now and it's still shifting like a new trans. I am so amazed I tell everyone about this product. Thank you so much for this wonderful product.
