You're a savior, unplugging the Rabs saved me a trip to the transmission shop. I've tried everything I could think for OD flashing lights and thundering shifts. I replaced the VSS, MAP and neutral safety switch. followed miles of harness, unplugged anything i could find to clean and hit with dielectric grease but this has my truck shifting like new!! Thank you.

Well unplugging the RABS didn't last long. Did about 60 miles and the whole thing started again. peeked into the diff through the vss hole and the tone ring is rusty. new one came today, i'll keep updating as things resolve or not.
