    3. NOTE: Do not bend the manual valve rod clip when removing the manual valve rod. If the manual valve rod clip is bent back to remove the manual valve rod instead of sliding it off, the manual valve rod clip will become permanently distorted causing total loss of transmission control or transmission failure. If the manual valve rod clip is bent, install a new manual valve rod clip.
  3. Remove the manual valve rod. Pull the manual valve rod clip tab out of the TR sensor, slide the manual valve rod clip off of the manual valve rod and remove the manual valve rod from the TR sensor and the manual valve.
