Trans Fail Safe, left me stranded


Might need the best minds on this one as I'm about done with this money pit.

P0720 Output Speed Sensor error code, along with BMW codes 121, 120, 132, 106. 1st Gear Ratio, 2nd Gear Ratio, Input/Turbine error in no particular order.

Car is in limp mode and had to get towed to mechanic. Diagnosed battery and alternator and both are fine. Ignition Switch replaced last year. Switched camshaft position sensor last month and everything was gravy until... now.

What's next? Change output speed sensor? Anyone experience this before? Sort of sad at 150,000KM one owner.
