Check that the transaxle control module (TCM) commands the pressure control solenoid valve (PCSV) correctly when Drive or Reverse is
selected by either of the following methods. If not, replace the TCM.

A.

Connect the scan tool to the DLC and select "Transaxle" menu, then select "Data". Check that PCSV duty reads 50-95% momentarily when
Drive or Reverse is engaged.

Install the J39853 automatic transaxle tester. Observe the PCSV indicator light when Drive or Reverse is engaged. The light should
illuminate briefly during gear engagement.

If Steps 1 - 6 indicate that all components are within specification and no DTCs are found, compare the customer's vehicle with another vehicle of
the same year and model. If the customer's vehicle engagement shock is:

^

Similar to other vehicles - advise the customer that the engagement is normal for that model/year.

^

More noticeable than other vehicles - replace the TCM for vehicles produced PRIOR to the effective date shown in the PARTS
INFORMATION table. For all other vehicles, replace the transaxle.
