700r4 overdrive?
I have 1985 C10 with a305/700r4 non ESC. Can anyone answer why in overdrive it makes a humming noise and when it’s disengaged it goes away? Also I noticed that when I disconnected the knock sensor the over drive did not work and when plugged back in it works? I got rid of all the ESC...- ramos78641
