    Double overdrive is an overdrive driving an overdrive. Like an RTOO14613. Over drive in the main case and auxiliary section. A set of boxes both with overdrive.


    Maybe cuz the 15 over was against the dash they call it double over......I gotta say it chaps my ### when they do lol.

    A 15 should be .79 OD, and a newer 13 is .73.

    Ended up being an 8LL they shipped. It's a .73 or .74 OD, so I'm running the same that I was with the 10. Supposed to give them a call tomorrow to set up getting a 13 switched out. I'm going to run this one until I can get the replacement swapped. At least this is a good tight transmission, and I got rid of most of my noises and vibrations. But, the main one I was after is still there so has to be in a rear or the power divider.
     
    Oxbow Thanks this.
