NOTE: If DTC P0811 only is present diagnose it first. If DTCs P0686, P0871 for P0961 are present as well, diagnose them first before P0811.	Carry out on-board diagnostic tests. Refer to INTRODUCTION - GASOLINE article for diagnosis and testing of the TCM. GO to PINPOINT TEST E , GO to PINPOINT TEST F and GO to PINPOINT TEST G to Pinpoint Test PINPOINT TEST I . Repair as required. Clear DTCs, road test and rerun on-board diagnostic test.
Fluid	-
Incorrect fluid level (low)	Adjust fluid to correct level.
Halfshaft	-
Splines - worn, damaged	Inspect for damage. Repair as required.
Shaft - misassembled, incorrect	-
Shift Linkage	-
Damaged or out of adjustment	Inspect and repair as required. Verify linkage adjustment. Refer to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS .
NOTE: The transmission control module (TCM) is integrated into the mechatronic assembly. If installing a new transaxle or a mechatronic assembly, the TCM will need to be checked and recalibrated (reflashed) to the latest level calibration available. Transmission Range Sensor	-
Incorrectly installed	Bolts loose. Tighten to specification.
