Shift Quality

IMPORTANT: The assessment of shift quality is an individual, subjective matter. Take note of how the customer describes the complaint and how the customer 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

Perform the general procedures described in the diagnostic section of this book.
Perform a test drive to answer the following questions:
- Under which driving situations does the shift quality condition arise?
- To which shifts does the condition apply?
- Is the condition reproducible within a short period, or has the condition only occurred sporadically or on a single occasion?
Inspect the oil level and the oil quality.
Check the fault memory.

Condition	Action
Rapid pressure build-up in the clutch	This is an operating error caused by selecting a position several times in quick succession.
Jerk when the parking lock is released	Refer to the Noise table in this procedure.
Incorrect electronic transaxle control module	Refer to the data status for the transaxle control module.
The accelerator pedal is in an indefinite position between full throttle and kick down.	Inform the customer to choose clearly between kick down and full throttle. Inspect the setting according to the engine repair instruction. Adjust, if necessary.
Control overlap between two clutches during a shift	This is a production status. Convince the customer.
Temperature sensor - not fault memory	Refer to Drive Range - Fourth Gear, Emergency/Substitute Mode or Drive Range - Third Gear, Emergency/Substitute Mode .
Incorrect kick down setting	Inspect the following conditions: Verify that the floor mat is not obstructing the accelerator pedal. Inspect the kick down for proper operation.
