46RE ticks in all gears except reverse

No speedo gear in this one, electronic trans with a speed sensor. The TC shouldn't move forward in park or neutral? Makes noise there as well.
My 1996 46re has a speedo gear inside, I had to change it when going to 3.92's. Speed Sensor, sure, it wont go into overdrive otherwise , but speedo gear is still there...at least on mine.
