Product Information
• High protection against freezing, corrosion, and cavitation
• Excellent lubricating properties, high ageing resistance, and high wetting and adhesion properties
• Prevention of deposits and foam formation
• Compliance with the requirements of vehicle manufacturers

Vehicle Repairs. We've Got What it Takes.
Only the right oil can guarantee continuous gear lubrication. Gear oils from febi are therefore precisely matched to the special requirements of vehicle manufacturers.

In addition to their favourable friction behaviour, febi gear oils offer optimal resistance to low temperatures and guarantee the best possible corrosion protection.

Quality by Conviction
Oils from febi are not universal products, but rather are tailored to the special requirements of vehicle manufacturers.

The gear oils offered consist of the most efficient base oils and modern additives. Thanks to their thermal stability, the oils are ideally resistant to ageing and provide maximum wear protection in all operating conditions.

Optimal Packaging Design
Gear oils from febi are an excellent choice. This is demonstrated not only by the quality - in many cases, febi transmission fluid even exceeds the requirements of vehicle manufacturers - but also by the user-friendly packaging design.

The clear labelling of the products through the use of color-coding makes their identification simple. Special recessed grips on the recyclable, leak-proof PE plastic bottles make filling noticeably easier. Viewing strips also provide information about the current filling level at all times.

About Gearbox / Transmission

Porsche Gearbox & Transmission Parts

At Design911, we stock a comprehensive range of gearbox and transmission parts for all Porsche models — from early classics to the latest performance cars. Whether you need a small replacement part, a complete clutch kit, or a full gearbox rebuild, our catalogue covers everything to keep your Porsche shifting smoothly.

Our range includes:

Accelerator Cables Clutch Kits & High-Performance Clutch Kits Clutch Release Bearings, Cables & Guide Tubes Clutch Ring Gears, Forks, Levers & Bolts CV Joint Kits & CV Boots Driveshafts / Cardan Shaft / Prop Shaft Gearshift Control Parts & Linkages Complete Gearboxes & Porsche Gearbox Parts Gearbox Gasket Sets & Mounts Gearbox Oil, Sumps & Oil Pans Sportomatic Transmission Parts Differentials & Limited-Slip Units Flywheels & Torque Converters Speed / Reference Sensors Transmission Oil Coolers & Associated Parts

From OEM-spec replacements to performance upgrades, we provide genuine Porsche parts and aftermarket alternatives — all quality checked and shipped worldwide.

Symptoms of a Bad Gearbox / Transmission

Recognising issues early can save money and prevent further damage. Look out for these tell-tale signs:

  • Whining or Clunking Noises – humming, buzzing, or clunking often indicates failing bearings or internal wear.
  • Lack of Response – delayed gear changes or hesitation means the transmission isn’t engaging correctly.
  • Burning Smell – often caused by overheating transmission fluid or internal friction.
  • Leaking Fluid – transmission fluid under the car is one of the clearest warning signs.
  • Grinding Gears – in manuals, this can point to a worn clutch or synchronizer issues; in automatics, it may feel like rough, noticeable shifts.

Signs of a Bad Clutch

The clutch is critical for changing gears — and like all mechanical parts, it wears out over time. Depending on your driving style, a clutch can last anywhere from 50,000 to 100,000 miles or more. Stop-start city driving, frequent gear changes, and aggressive driving can shorten its life.

Common symptoms of clutch failure include:

  • Spongy, sticking, vibrating, or loose clutch pedal
  • Squeaking or grumbling noises when pressing the clutch
  • Engine revs but poor acceleration (slipping clutch)
  • Difficulty engaging gears smoothly
  • Momentary loss of acceleration during shifts

If you notice these issues, it’s best to arrange an inspection or replacement before further damage occurs.

Gearbox Fitment, System Compatibility and Quality

Correct fitment and system compatibility are essential to ensure smooth gear changes, efficient power transfer, and long-term reliability. Every component is engineered to meet original Porsche specifications, maintaining correct tolerances, mounting accuracy, and full system integration. 

This includes critical sealing and structural elements such as gearbox gasket sets, seals and lock nuts, along with essential mounting solutions like gearbox mounts, both of which play a key role in reducing vibration and maintaining drivetrain stability.

Matched to Original Porsche Transmission Standards

Transmission systems rely on precise engineering alignment to maintain performance and durability. Factory-correct specifications ensure that every component works in harmony, preserving shifting accuracy and reducing unnecessary wear across the drivetrain.

Designed for Complete Drivetrain Integration

Modern Porsche transmissions depend on coordinated operation between control, lubrication, and mechanical systems. Smooth shifting performance is supported by correctly specified gearshift control parts, while long-term reliability depends on proper lubrication delivered through gearbox and differential oil and contained effectively within gearbox sumps and oil pans.

Supporting Differentials, Transfer Systems and Drivetrain Control

Advanced Porsche drivetrain layouts incorporate both front and rear torque distribution systems, including the front differential and rear differentials. These are supported by specialised assemblies such as the transfer box and Sportomatic systems, which help manage power delivery across different driving conditions and vehicle configurations.

Transmission Monitoring and Cooling Systems

To maintain consistent performance and protect drivetrain components, modern systems rely on accurate monitoring and temperature control. Key supporting parts include gearbox transmission sensors, transmission cooling systems, and fluid hoses and pipes, all working together to regulate operating conditions and ensure long-term transmission reliability.


Porsche Gearbox & Transmission Maintenance and Longevity

Transmission components experience constant mechanical load and require regular inspection to maintain performance and reliability.

Component Typical Service or Inspection Interval Common Signs of Wear
Clutch Kits Inspect every 60,000–100,000 miles Slipping, poor engagement, vibration
Flywheels Inspect during clutch replacement Noise, excessive play, vibration
Gearbox Oil Replace every 40,000–60,000 miles Rough shifting, overheating
Driveshafts Inspect every 60,000 miles Vibration, knocking under load
CV Joints Inspect every 40,000–60,000 miles Clicking noises, grease leaks
Gearbox Mounts Inspect every 5–8 years Excess movement, vibration
Differential Components Inspect every 60,000 miles Noise, uneven power delivery
Sensors Inspect every 5–10 years Warning lights, incorrect readings
Regular servicing ensures smooth shifting, reduced wear, and long-term drivetrain reliability.

Porsche Gearbox Performance and Upgrade Advice

Maintaining or upgrading your Porsche gearbox improves driving precision, responsiveness, and reliability under load.

Benefits of Preventative Replacement and Upgrades

  • Improved Gear Change Precision: Replacing worn clutch and gearshift components restores smooth, accurate shifting and driver control.
  • Enhanced Power Transfer: Upgraded clutch kits and drivetrain components improve torque handling and reduce power loss.
  • Increased Reliability Under Load: High-performance and OEM-spec components are designed to withstand increased stress, especially in tuned or track-focused vehicles.
  • Optimised System Compatibility: Using correctly specified gearbox and transmission parts ensures seamless integration with existing systems.
  • Reduced Long-Term Costs: Preventative maintenance reduces the risk of major gearbox failure and costly repairs.

Design911 supports complete gearbox maintenance, rebuilds, and performance upgrades. From clutch replacements to full transmission systems, our range ensures precise fitment, durability, and a refined Porsche driving experience.
