I've got this 07.5 van that I use for work and a daily driver, I was looking to tune it with efi live and do some transmission work so it'll hold up.. Billet Torque converter and transgo hd2 kit is what seems to be the ticket for these transmissions as far as I've read..I was thinking about running it at the track occasionally when I can unload my tools for the weekend.. Anyone have experience with this transmission and it's limitations? I'd like to take it apart only once... Thanks
