FAQs

1. Which Audi models is this transmission mount compatible with?
This mount fits the Audi A4 B6 and B7 generation, particularly those with 5-speed manual transmissions. OEM part 8E0399105HB covers a wide range of these models.

2. What is the purpose of a gearbox (transmission) mount?
The gearbox mount secures the transmission to the chassis, reducing unwanted movement under torque and isolating vibrations. It helps maintain proper gear alignment and ensures that the drivetrain runs smoothly.

3. What are the signs of a failing gearbox mount?

• Clunking or knocking when changing gears

• Excessive vibration in the cabin, particularly at idle or during acceleration

• Gear shifter wobble or misalignment under load

• In severe cases, the gearbox may sit at a slightly different angle after mount failure

4. Is this an OEM or aftermarket part?
This version is OEM-equivalent aftermarket part and is referenced under the genuine part number 8E0399105HB. 

5. How hard is it to install this mount?
Replacing a gearbox mount generally involves:

• Supporting the transmission (or engine) safely (jack / transmission jack)

• Unbolting the old mount from the chassis and gearbox

• Installing the new mount and torqueing bolts to spec
  If you’re not confident doing this kind of job, a professional mechanic is recommended.

6. Will replacing this mount fix shifter or vibration issues?
Often, yes — if the mount is worn or broken, replacing it can resolve:

• Clunks when shifting

• Vibration or shudder in the drivetrain

• Misalignment in the gear lever feel
  However, if the problem is from other worn mounts or linkage, you may need to address those too.

7. Does this part come with a warranty?
Our all products are protected by a upto 10 year worry-free warranty depending on Part and We have a 180-day return policy, which means you have 180 days after receiving your item to request a return. 

8. Is it safe to keep driving with a damaged gearbox mount?
You can, but it’s not ideal: a failing mount can allow excessive movement of the transmission, which stresses other components (driveshaft, linkage, other mounts) and may lead to further issues or noise.

9. Why choose this mount from a specialist parts supplier?

• OEM spec quality ensures correct fit and performance

• Helps restore factory-like drivetrain stability

• More affordable than some genuine dealer units
