Far left field, but how is the bushing for the zbar that the shifter rod is supported on the frame? If that bushing is gone or the cab has really settled, this will throw off the reading in the truck. My old plow truck the bushing went bad, and the zbar fell out, causing park to end up actually reverse on the indicator.
Hose clamp kept the rod in place, and the indicator worked as noted.
Like I said, far left field, but worth a quik look
