I am installing a 3550 TKO in my Bullitt and removing the 3650. I seem to have everything figured out except for the speedo hook-up. The TKO xmission will have a gear/mechanical output. Ofcourse the '01 computer needs an electronic input. Anyone know the solution or source of information on this? Gotta believe I am not the first one to cross this bridge with the history of the 3650, and no, I really don't want to go to the heavier and more expensive T56. Thanks!
