Replaced auto trans in vehicle due to broken wave plate/ washer (no reverse or drive). after installed, used transmission will not engage in Drive or Reverse unless the engine is revved and when RPM drops to near idle, it drops back out of gear. Has Code 23 (P0720) Output Shaft Speed Sensor Fault. What is the likelihood that a new OSS will resolve this issue.
