ROUTINE 288

OTHER CONCERNS: TRANSMISSION CONTROL MODULE SOFTWARE

Possible Component	Reference/Action
288 - ROUTINE
Shifting and Driveability Concerns
Transmission control module not at current software level	Reflash the transmission control module to current software level.

ROUTINE 207

ENGAGEMENT CONCERNS: NO FORWARD AND/OR NO REVERSE

Possible Component	Reference/Action
207 - ROUTINE
No Forward, No Reverse, No Forward or Reverse	-
Shift linkage damaged or out of position	Refer to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS .
-	Using a scan tool, check shift lever position.
Incorrect neutral switch position	Carry out neutral position learning. Refer to NEUTRAL POSITION LEARNING .
	Disconnect the transmission control module (TCM) electrical connector. If concern still exists, this indicates an internal mechanical problem. Connect the TCM and carry out pressure checks.
	If concern is resolved by disconnect the TCM, this indicates an electrical concern. Install a new TCM. Refer to TRANSMISSION CONTROL MODULE (TCM) . Check wiring harness (external and internal) valve body connections.
