Transmission Noise Concerns

WARNING: This page is about a different variant/trim than selected.

Check the engine and transmission mountings for sufficient clearance to the transmission and the body.
Any other noise excluding shift noises.
Road test the vehicle. Carry out the checks in the following table and record the results.

NOTE: If the answer is "Yes" to one or more of the tests, the transmission must be removed and the dual mass flywheel tested. For additional information GO to Pinpoint Test A

Item No.	Situation, Test / Diagnosis	Yes	No
1	Driving situation:	0	0
	Road test the vehicle. Select 5th or 6th gear and fully press the accelerator pedal to obtain maximum engine torque.
	Diagnosis:
	Are there extremely harsh vibrations from the powertrain? Vibrations disappear when the accelerator pedal is released briefly.
1a	Driving situation:	0	0
	Road test the vehicle. Drive the vehicle in simulated "stop and go" mode (1st gear). Check for transmission rattle during gentle acceleration and deceleration.
	Diagnosis:
	Are there noises from the powertrain in driving situations between idling speed and a maximum of 2000 RPM which occur at a specific, vehicle-dependent vehicle/engine speed?
2	Driving situation:	0	0
	Raise and support the vehicle. REFER to: Jacking and Lifting - Overview . Check all engine/transmission and exhaust mountings with the engine not running, while starting the engine and when it is idling.
	Diagnosis:
	Does the engine/transmission shake severely or make rattling noises during starting? Is there a longer time before the engine reaches idle speed? Install new components as necessary (engine/transmission or exhaust mountings) and repeat the test.
3	Driving situation:	0	0
	Check the front axle driveshafts and the manual transmission. Lock the wheels and apply the parking brake. Start the engine, engage 1st gear and slowly release the clutch pedal while the engine idles.
	Diagnosis:
	Engine speed does not drop, power not transferred, vehicle does not move.
4	Driving situation:	0	0
	Start the engine, place the gear lever in the neutral position and slowly release the clutch pedal. Stop the engine.
	Diagnosis:
	Hard metallic noise as the engine stops, coming from the manual transmission during the last engine revolution before the engine finally stops, is NOT caused by the dual mass flywheel.
	If a clattering noise is detected as the engine is switched off with the clutch pedal pressed, check the transmission housing for grease residues (more than 2 grams) from the dual mass flywheel. Remove the starter motor and check the bell housing. REFER to: Starter Motor .
