Symptom ActionPossible Cause
NoiseThe Engine’s Torsional Vibrations are
Being Transmitted to the Drive ShaftsS At low speeds in fourth gear, vibration can
arise (driving at too low an engine speed)
S Noise is functionally unavoidable; due to toler-
ances. Convince the customer.
NoiseTorque Reaction Strut LooseS Check mounting and repair if necessary.
Shift quality
Notice :
– The assessment of shaft quality is, to a large ex-
tent, 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 ques-
tions.
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 mea-
surement block data.
Symptom
Possible CauseAction
Shift QualityRapid Pressure Build–up in the ClutchS Operating error (position selected several times
in quick succession).
Jerk When Parking Lock Is ReleasedS Refer to ”Noise” in this section.
Incorrect Electronic Transaxle Control
moduleS Check the data status for transaxle control
module ; refer to ”TCM” in this section.
Emergency/Substitute Program Has
Been ActivatedS For checking and remedial action, refer to
”Emergency/Substitute program” in this sec-
tion.
Accelerator Pedal in Indefinite Position
Between Full Throttle and Kick DownS Persuade customer to choose clearly between
kick down and full throttle
S Check setting according go engine repair in-
struction ; adjust if necessary.
Control Overlap Between to Clutches
During ShiftS Production status
S Convince the customer
Temperature Sensor
(Not Fault Memory)S Check function according to ”Emergency/Sub-
stitute program” in this section.
Kick Down Setting IncorrectS Check
A) Floor mat is obstructing accelerator pedal
B) The kick down setting as described in the
Engine Section.
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
