Gearbox Mounts
By OE Match
- Porsche 914 (1970-1976)
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.

OEMatch Gearbox Mounts — Engagement, Smoothness, Control
OEMatch gearbox mounts for Porsche models reduce drivetrain vibration and help maintain transmission alignment under load. OEMatch gearbox mounts are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable. Use these mounts to restore refined gearshift feel and to protect adjacent drivetrain components.
Available Types
- Rubber-mounted gearbox mount for road use
Understanding OEMatch Gearbox Mounts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original gearbox mounts.
OE (Original Equipment) refers to parts matching original specifications for the gearbox mounts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM gearbox mounts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Gearbox mounts secure the transmission to the chassis while isolating vibration and absorbing torque movement. They control drivetrain movement under acceleration, braking and cornering and help maintain driveshaft and linkage alignment. When mounts deteriorate, you may notice clunking, increased vibration or harsher shifting; prolonged movement can place additional load on exhaust, shafts and linkage components.
Benefits Include
- Restores smooth, vibration-reduced gear changes
- Maintains correct driveshaft and linkage alignment
- Reduces stress on transmission and adjacent components
Why Gearbox Mounts Wear and Fail
- Rubber deterioration and cracking from heat and age
- Oil contamination that softens mount compounds
- Fatigue or fluid loss in hydraulic-mounted designs
The Importance of Replacing with OEMatch Gearbox Mounts
Replacing worn gearbox mounts restores drivetrain stability and smoother shifting, reducing noise, vibration and harshness that affects comfort and control. Timely replacement helps prevent secondary damage to exhaust, linkage and driveshaft fittings and supports predictable throttle response and handling on Porsche models.
Advantages
- Replacement rubber and reinforced designs for varied use
- Options suitable for classic and modern Porsche models
- Direct-fit alternatives made to original-spec dimensions and tolerances
