personal preforance mostly
I like the hard shifts and full manual shift on the street
its just whats recomended most often
along with the billet servos and the eagle red clutches and coleen steels
the billit servos can be had from board member and sponser ROBMC IIRC..look for the add flashing on top of page also
CRT is the place for the kits, they are a sponser here on the board
give john a call he can help you with the ?s
look for the add at the top of the page
the trans go III kit is for full manual shift valve body
you may very well only need the tf-I shift kit
I am no guru but I am saving up for the bullit proof 727 from john at crt
A&A transmission is another here on the board thats top shelf
maybe john kunkle will chime in he is a guru also with good advice
