8. Install the control valve body. (See «CONTROL VALVE BODY REMOVAL»(ref-177779-S42283433762005060700000) .)
9. Install the under cover.
10. Connect the negative battery cable.
11. Install the battery duct and battery cover. (See BATTERY REMOVAL/INSTALLATION .)
12. Add ATF and, with the engine idling, inspect the ATF level and inspect for leakage. (See «Automatic Transaxle Fluid (ATF) Level Inspection»(ref-177779-S06025643442005060700000) .)
13. Perform the mechanical system test. (See «MECHANICAL SYSTEM TEST»(ref-177779-S05823164852005060700000) .)

Repair procedure

1. Before power flushing, inspect the hoses/lines and clamps. Power flushing must begin with back flushing followed by forward flushing to quickly dislodge the restriction. If back flushing is not performed before forward flushing, the restriction could further reduce the ATF flow through the internal mesh type baffle of the cooler and flushing will not be effective or possible.
