transgo is the most complete kit for the do it yerselfer. do the od servo at the same time, and watch that when you reinstall the od servo that you get it in the band lug otherwise you shift 1-2-3-neutral. not cool, i'm speaking from experience.
transgo is the most recognized brand for trans. shops because their products are not only built for performance, but they fix common known issues with the transmissions they are designed for.
