Gearbox Mount.

The OE Match Gearbox Mount is a replacement rubber transmission mounting for Porsche 914 four-cylinder models.

Fits:

• Porsche 914-4 1970 - 1976

Diagram Ref No 36

Installed between the gearbox/transaxle and the vehicle structure, the mount supports the transmission while isolating normal drivetrain vibration and movement from the chassis.

The Porsche 914's engine and transaxle generate continuous vibration, torque reaction and movement as the vehicle accelerates, decelerates and changes gear. The gearbox mounts allow a controlled amount of movement while keeping the transmission correctly located.

Over time, the rubber within the original mounts can harden, crack, separate or collapse. When this happens, the gearbox can move more than intended, potentially causing increased vibration, knocking noises, less precise gear selection and additional stress on surrounding drivetrain components.

Replacing worn mounts helps restore correct gearbox support, drivetrain alignment and the smoother, more controlled behaviour intended by the original mounting system.

What This Product Does:
The Gearbox Mount supports and locates the Porsche 914 transaxle while isolating drivetrain vibration from the body.

Its main functions are to:

• Support the gearbox/transaxle.
• Maintain correct drivetrain position.
• Control transmission movement during acceleration and deceleration.
• Absorb normal drivetrain vibration.
• Reduce vibration transmitted into the chassis.
• Help maintain correct gear-selector geometry.
• Reduce shock loading on surrounding drivetrain components.
• Support smooth power delivery.
• Replace cracked, hardened, collapsed or separated original mounts.

Symptoms Of Wear Or Failure:
Common symptoms can include:

• Excessive drivetrain movement.
• Gearbox visibly moving under load.
• Clunk when accelerating.
• Clunk when lifting off the throttle.
• Increased vibration through the body.
• Increased vibration at idle.
• Harshness through the cabin.
• Gear lever movement during acceleration or deceleration.
• Less precise gear selection.
• Knocking from the rear drivetrain area.
• Rubber visibly cracked.
• Rubber separating from the metal section.
• Mount sagging or collapsing.
• Oil-soaked or deteriorated rubber.
• Transmission sitting incorrectly.

Why Replacement Matters:
Replacing worn Gearbox Mounts helps restore:

• Correct transmission support.
• Controlled drivetrain movement.
• Improved drivetrain alignment.
• Reduced vibration.
• Reduced knocking and clunking.
• More consistent shift-linkage geometry.
• Smoother power delivery.
• Reduced stress on surrounding components.
