Where is the rear speed sensor located?? I saw a sensor on top of the front of the rear diff and figured since I have rear abs only that was it. I upgraded my tranny with a bd diesel torque converter, new flexplate, accumulator body, filter and external filter. Also took out stock cooler up front and added a derale cooler w/fan and 180 degree thermostat a few years ago. I haven't had any tranny problems but light flashes intermittently causing no issues and o/d switch still works while light is flashing you just can't tell whether it's on or off.
Could this light flashing have anything to do with my recent power loss, rough idle and missing 1 and 8 cylinders?? lol . . . I wish . . . I am hoping it is just my ICP sensor . . . going to pick one up tomorrow!
