• 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. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/TRANSMISSION CONTROL MODULE - STANDARD PROCEDURE)
• Use the EATX OBDII task manager to run Good Trip time in each gear, this will confirm the repair and to ensure that the DTC does not re-mature.

• Refer to the Transmission category and perform the appropriate symptom. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - DIAGNOSIS AND TESTING)
