Main Control: Installation

    NOTE: If cleaning of the main control assembly or inspecting the valves, refer to Main Control Assembly . If installing a new main control assembly continue with this procedure.
    NOTE: Make sure that the manual pin (part of the TR sensor) is correctly installed in the manual valve.
  1. Position the TSS, OSS and TR sensor wiring harnesses aside and install the main control valve body.

    CAUTION: Do not handle the solenoid body in the lead frame area or by the screens of the solenoid body filter or damage to the solenoid body can occur.
    CAUTION: Use care not to break the alignment tabs when installing the solenoid body filter. Damage to the transaxle will occur if the solenoid body is not correctly aligned.
    CAUTION: Make sure that the filter passage areas are clean of foreign material before installing the filter. Damage to the transaxle will occur if the filter passages are not clean.
  4. Install a new solenoid body filter assembly by pushing it straight down on to the alignment tabs.
