45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1
For a complete wiring diagramRefer to Section 8W.
1.
Perform the following after completion of a diagnostic repair:
After completion of the Transmission Verification Test, the Powertrain Verification Test must be per-
formed.
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 DTC’s.
With the scan tool, perform a BATTERY DISCONNECT, this will clear the DTC EVENT DATA
With the scan tool, display Transmission Temperature. Start and run the engine until the Transmission Tem-
perature is HOT.
Check the Transmission fluid level and adjust if necessary. Refer to the Service Information for the Fluid Fill
procedure. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE/FLUID - STANDARD
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 Kmh (60 mph); make fifteen to twenty 1 to 2, 2 to 3, 3 to 4 upshifts andfor545RFE,4to5.
Perform the following shifts with speeds below 40 Kmh (25 mph); make five toeight wide open throttle kick-
downs to 1st gear. Allow at least 5 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, performthe 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.
Were there any Diagnostic Trouble Codes (DTCs) set during the road test?
Ye s>>
Refer to the Transmission category and perform the appropriate symptom. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - DIAGNOSIS AND TESTING)
No>>
Repair is complete.
