What This Product Does
The hydraulic mounts connect the gearbox assembly to the vehicle structure, supporting its position and damping vibration transferred through the drivetrain. Their controlled movement also helps maintain the intended alignment of the transmission, linkage and surrounding components during acceleration, braking and gear changes.
Functions
- Supports the gearbox in its installed position
- Damps vibration transmitted from the drivetrain
- Controls transmission movement under changing loads
- Helps maintain gearbox and linkage alignment
- Reduces stress caused by excessive drivetrain movement
Technical Details
- Part number: 98137504902
- Contents: two hydraulic gearbox mounts
- Mount type: non-dynamic hydraulic mounting
- Application code: PR:-140
- For vehicles without option code 140, Porsche Active Drivetrain Mounts (PADM)
- Diagram group: transmission suspension and threaded joint
Symptoms of Fault
- Increased vibration through the cabin at idle or low speed
- Thumps or clunks when engaging gear or changing throttle load
- Noticeable drivetrain movement or shunt
- Less precise or inconsistent gear-change feel
- Exhaust or nearby components knocking as the drivetrain moves
- Visible mount deterioration, collapse or hydraulic leakage
Why Replacement Matters
Age, heat cycling and repeated drivetrain loads can reduce a hydraulic mount's ability to control gearbox movement. Replacing worn mounts as a matching pair helps provide balanced support, restores the intended isolation between the transmission and body, and limits avoidable strain on the linkage, exhaust connections and related components. Other potential causes of vibration or poor shifting should be checked before replacement.
FAQs
- Are these mounts suitable for cars with PADM?
No. This set is specified for vehicles without Dynamic engine mounts (PADM), identified by application code PR:-140. - Does the set contain both required mounts?
Yes. The supplied diagram data specifies a vehicle quantity of two, and this package contains two mounts. - Will replacing the mounts repair gearbox crunching?
Not necessarily. Worn mounts can affect drivetrain movement and shift feel, but crunching may also indicate clutch, linkage or internal transmission wear. - Should related hardware be inspected?
Yes. Check the mounting consoles, sleeves, nuts and bolts during installation and renew any items that are damaged or specified as one-time-use.
