I've had AutoRx in the tranny of a 93 Taurus (with a bit over 200k miles on the car) for 600 miles now, and in the tranny of a 99 Taurus (with a almost 100k miles on the car) for 800 miles now, and the so far the stuff is working well, very well. Shudder is pretty much gone in the 99, is almost gone in the 93, and the shisfts on both cars is more definate and crisp. The 99 had a noticeable clunk during what I think is called 'coast down', when slowing down to stop, and it seems like it might be getting cured as I don't notice it as much at all. It'll be interesting to see how they do with new fluid.
Anyway, it works so well that I'll consider adding some at the last 1000 miles before each fluid change.
