Installation [06/2018 - ]: Procedure

  1. INSTALL PARK/NEUTRAL POSITION SWITCH ASSEMBLY 
    NOTE:

    Both the park/neutral position switch assembly and transmission control shaft lever are available in two different shapes due to design changes. As they are not compatible with each other, when replacing the park/neutral position switch assembly, make sure to also replace the transmission control shaft lever as a set.

    1. Temporarily install the park/neutral position switch assembly to the automatic transaxle case sub-assembly with the 2 bolts.
      NOTE:

      Before installing the park/neutral position switch assembly, remove any dirt or rust on the manual valve lever shaft sub-assembly. Be sure to install the park/neutral position switch assembly straight along the manual valve lever shaft sub-assembly while being careful not to deform the plate spring that supports the manual valve lever shaft sub-assembly. If the plate spring is deformed, the park/neutral position switch assembly cannot be installed correctly.

    2. Temporarily install the transmission control shaft lever to the park/neutral position switch assembly.
    3. Turn the transmission control shaft lever clockwise until it stops, then turn it counterclockwise 2 notches.
