Hey y’all got a 621e 2Db00747 has developed a random shift issue. Sometimes it gets stuck in a gear and won’t shift up or down , sometimes it’s stuck in reverse and moving shifter does nothing sometimes it just won’t shift. We can turn off the master and 50%!of the time that will fix it for awhile. Sometimes it shift perfectly for days and then acts up again. Today it wouldn’t work for 5 hrs and then after messing with it it’s running great(scratching my head)today I tested the shifter switch by grounding the pins and the up/ shift solenoids are clicking way as I move the selector. Also inspected wire harness and it looks good where I can follow it. After all that it now shifting and running great. Any suggestions?
