    I just swapped my zf meritor automatic out to a eaton manual 10spd. I'm having a problem getting the speed sensor to read. I did check oms on the sensor, and it was 1780 not sure if that correct, or not.

    I got to speed sensor that came with the 10spd. I just figured I had a bad sensor, or something wrong with the wiring. I first hooked up to the wiring for the manual transmission, and that didn't work, then I wired it into the wiring harness for the automatic transmission. Still nothing. I wonder if the sensor you used will work in a 10spd too.

    That I don't know.They did alot of rewiring so I'm not certain.I do know when I first got it back the speedo worked then about 50 miles down the road it stopped.Called them and they said something about the teeth on the gear.Took it back they drilled out the old speedo and replaced it and worked perfectly ever since.

    I was told, I needed to get the ecm reflashed for the manual. I guess, I'm going to try that tomorrow, if I can find soneone to do it.

    DDEC ECM must be reprogrammed with DDRS to magnetic sensor (now J1939 from MID 130 is set)
