    Default 4R75E J-mod

    I read a lot about it, but I never find concrete info about sense of making modification on 4R75E. If I understand correct late tranny's have upgarde separator holes, etc. What should I do, to make my gearbox a little bit more "modern" in action? I would like to minimize slippage effect and speed up up' and downshifts. I heard that sonnax have a lot performance parts for AOD's but I don't know what should I order.

    Tune is the biggest thing you really can do beyond maybe a higher stall torque converter without doing a full transmission build. Tune alone will make it feel like a more modern design.

    Tune via OBD ? I wonder if anyone in my country know how to tune this gearbox - it's not VW or Merc...

    I am sure marty at MO's speed shop can do a tune for you. the only question I have is about the difference in fuel between the 2 countries and how it will affect the timing curve.

    I spoke few months ago with Marty - He told me that He can make program for me, also about fuel differences. I plan to make tune in 2020 season.
