  25. Make sure that the park pawl actuator rod does not become disengaged from the park pawl and the abutment by keeping the end of the park pawl actuator rod behind the machined valve body mating surface of the transaxle case. If the park pawl actuator rod becomes disengaged from the park pawl and the abutment, transaxle removal and disassembly is required to reinstall the actuator rod.
    26. NOTE: Make sure that the park pawl actuator rod does not become disengaged from the park pawl and the abutment or the park pawl will not lock the output shaft and transaxle removal and disassembly will be required to reinstall the actuator rod.
  26. Remove the TR sensor.
    1. Slide the TR sensor down until the manual shaft is out of the transaxle case.
    2. Rotate the TR sensor detent plate counterclockwise, as viewed from below, until the plate rests against the transaxle case. Remove the park pawl actuating rod from the TR sensor and remove the TR sensor.
