Park / Neutral Position Switch -- Installation



1. INSTALL PARK/NEUTRAL POSITION SWITCH ASSEMBLY
HINT:
Make sure that the manual valve lever shaft has not been rotated prior to installing the park/neutral position switch as the detent spring may become detached from the manual valve lever shaft.
  1. Clean the bolt and the bolt hole.

  1. Apply adhesive to 2 or 3 threads on the end of the bolt.

    Adhesive:
    Toyota Genuine Adhesive 1344, Three Bond 1344 or equivalent
  1. Temporarily install the park/neutral position switch assembly with the bolt.

    HINT:
    Tighten the bolt to the specified torque when adjusting the park/neutral position switch assembly.
