I've installed the Transgo kit, I would recommend saving your $$$ and do a valve body. I don't think the kit makes that big of a difference on firming up the shifts. I did it as a temporary upgrade until I can sell off my left leg for a DTT or Goerands. sp? If the Kit is the way you have to go, it's not that difficult to do, just take you time and follow the instructions, and keep it clean, I mean very, very clean. Good Luck! I f there's anything else you want to know about it I would be happy to help!
