    Important: The tab on the sensor housing (46) fits into the recess on the case boss.

    Important: For drive sprockets with 35 teeth, use a black sensor housing. For drive sprockets with 32 or 33 teeth, use a natural colored sensor housing.

  1. Assemble the input speed sensor (46) to the transmission case.

Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
