    6L80 Random trans slip

    Hey there, I am having issues with a 6l80 that on random occasions feels like it is dropping in and out of drive and will buck when this happens. This usually happens at low throttle input and when cruising at steady speed. I have attached a log of the event happening, car was at a steady 110kph or so and cruising on a freeway when this happened.....any ideas would be much appreciated.
    Have dropped pan and replaced fluid and filter, found nothing in pan
    Dropped pan again and fitted the deep pan version with correct filter, Tested TECHM with a multi meter at the same time and found no issues

    Car is a VF SSV Redline 6.0L L77
