[NSTG8R]

Kind of a blue paste in a syringe. Stick the tip in the dipstick tube and squirt it in there. I did it at work in the parking lot because I couldn't for the life of me find the tranny dipstick (dark in the morning), and didn't notice any difference on the way home. The next morning on the way to work is when I actually noticed something was different, namely, less rev when the cruise engaged, and no downshift on the big hills on the way to work (first time ever). It's not supposed to be completely affective until 1500km (900 miles), which shouldn't hard to achieve since I log 400 miles a week back and forth to work. With our tranny capacity, it should probably use two tubes. I ordered two more, putting 1/2 tube more in the SVX, and putting the other 1 1/2 in my F250.
