For complete wiring diagrams, refer to SYSTEM WIRING DIAGRAMS .

1. Perform the following after completion of a diagnostic repair:
   • After completion of the Transmission Verification Test, the Powertrain Verification Test must be performed. 
   • With the scan tool check pinion factor (if equipped) for proper tire identification and program or reprogram if necessary.
   • Connect the scan tool to the Data Link Connector (DLC).
   • Reconnect any disconnected components.
   • If the PCM has been replaced or updated (flashed), or the transmission has been repaired or replaced, using the scan tool, perform a Quick Learn Procedure.
   • With the scan tool, erase all Transmission and Engine DTCs.
   • With the scan tool, perform a BATTERY DISCONNECT, this will clear the Event Data
   • With the scan tool, display Transmission Temperature. Start and run the engine until the Transmission Temperature is HOT.
   • Check the Transmission fluid level and adjust if necessary. Refer to the Service Information for the Fluid Fill procedure.
   • Road test the vehicle.
   • Perform the following shifts from a standing start with a constant throttle opening of 20 to 25 degrees to the speeds of 97 Km/h (60 mph); make fifteen to twenty 1 to 2, 2 to 3, 3 to 4, and 4 to 5.upshifts.
   • Perform the following shifts with speeds below 40 Km/h (25 mph); make five to eight wide open throttle kickdowns to 1st gear. Allow at least five seconds each in 2nd and 3rd gear between each kickdown.
   • Check for DTCs during and after the road test.
   • If after performing the road test, if any shift concerns are noted, perform the drive learn procedure for those affected shifts.
   • Use the EATX OBDII task manager to run Good Trip time in each gear, this will confirm the repair and to make sure that the DTC does not re-mature.
