Thanks for the info on the transmission.. never thought about it that way.
Changed the Cruise box on the fender. still doesn't work.

please correct me if i am wrong,
the trac control uses the wheel sensors to 'see' a difference in wheel speed.
there transmission will have a input speed sensor(shift points and the like).Or would that be engine speed(rpm)?
and an output sensor. is there only one 'output' sensor.
