Symptom DiagnosisOil Leakage
Notice: Careful localization of leakage points may make it possible to prevent incorrect or cost-intensive repairs.
Test Steps:
^ Thoroughly clean the transaxle, engine, and surrounding area (using a steam jet, for example).
^ To locate leakage, use a suitable identifying spray or similar product.
^ Depending on the amount of leakage, take the car for a short or a longer test drive
^ It may prove sufficient to place the car on a hoist and run the engine at idle speed to trace the leak.
^ If possible, determine exactly which type of oil is escaping.

Shift Quality
Notice:
^ 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?
^ Check the oil level and oil quality
^ Interrogate the fault memory and read out measurement block data.
Malfunction
Notice: The faults dealt with here concern transaxle functions such as "traction" (forwards and reverse) and all type of shifts. Entries will not always be made in the fault memory.
Test Steps:
Perform the general checks according to the automatic transaxle diagnostic procedure.
^ Test drive
^ Check oil level and quality
^ Interrogate fault memory
