Shift Quality

NOTE:

The assessment of shaft quality is, to a large extent, an individual, subjective matter. Take careful note of how the customer describes the complaint and of the manner in which he or she handles the vehicle and the controls.
A sudden deterioration of shift quality may also be caused by the transaxle selecting an emergency or substitute program.

Test Steps:

Carry out the general checks described in the automatic transaxle diagnostic information.
Perform a test drive to answer the following questions.

In which driving situations does the shift quality complaint arise?

To which shifts does the complaint apply?

Is the complaint reproducible within a short period, or has it only occurred sporadically or on a single occasion?
