I have used that one several times and others as well. I like that particular kit because it is "well balanced" as far as how it makes the trans shift. Some have a harsh 2nd and early high shift. while others are softer on 2nd but bang high gear. The 47-2 doesn't do that and is easy on internal parts. Shifts are firm and precise.
