Nag1 Transmission Verification Test - VER 1

WARNING: This page is about a different car, the 2005 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.

Reconnect any disconnected components.

Connect the scan tool to the Data Link Connector.

With the scan tool, erase ABS DTCs.

With the scan tool, erase PCM DTCs.

With the scan tool, erase TCM DTCs.

With the scan tool, display the Transmission temperature. Start and run the engine until the Transmission temperature is above 43° C (110° F).

Check the Transmission fluid and adjust if necessary. Refer to the Service Information for the proper Fluid Fill procedure.

NOTE: If internal repairs were performed and the shift quality is still poor, it may be necessary to check the internal repair.

If the TCM (EGS) is flashed or replaced, with the scan tool, perform a EGS initialization to relearn variant coding.

If internal transmission repairs are performed or replacement of the Transmission Control Module, perform a TCM ADAPTATION procedure. (Refer to ELECTRICAL/ELECTRONIC CONTROL MODULES/TRANSMISSION CONTROL MODULE - STANDARD PROCEDURE)

ROAD TEST PROCEDURE

Road test the vehicle. Make fifteen to twenty 1-2, 2-3, 3-4, and 4-5 upshifts.

Perform these shifts from a standing start to 72 km/h (45 MPH) with a constant throttle opening of 20 to 25 degrees.

With speeds below 40 km/h (25 MPH), make five to eight wide open throttle kickdowns to 1st gear. Allow at least 5 seconds each in 2nd and 3rd gear between each kickdown.

With the scan tool, read Transmission DTCs.
