Audi NEK Manual Gearbox

The NEK transmission code should be used as one of the primary references when matching this gearbox to a vehicle.

Audi A4 and A5 models were available with different manual transmissions depending on the engine, production year, drivetrain, market, and equipment level. Even when two vehicles appear similar, their gear ratios, mounting configuration, clutch components, driveshaft connection, and other transmission specifications may differ.

For this reason, buyers should match the NEK gearbox code with the original transmission before purchase rather than relying only on the vehicle model.

Vehicle Fitment

Potential applications include compatible:

• Audi A4 B8.5 Quattro
• Audi A5 B8.5 Quattro
• Manual-transmission configurations

The B8.5 facelift generation generally covers approximately 2012–2016, although exact model-year availability can vary by market, engine, and body style.

Important Fitment Information

Please verify all of the following before ordering:

• Transmission code: NEK
• Vehicle model and year
• Engine code
• Quattro drivetrain
• Manual transmission configuration
• Clutch and flywheel compatibility
• Driveshaft connection
• Axle/flange configuration
• Transmission mounting points
• Gear selector/linkage configuration
• OEM transmission part number

Do not purchase based solely on “Audi A4/A5 B8.5.” The NEK code and original transmission specifications should be matched before installation.

Compatibility With Engine

Manual gearboxes can differ according to the engine they were paired with. The correct transmission must be matched to the vehicle’s:

• Engine output
• Engine code
• Clutch diameter and design
• Flywheel
• Gear ratios
• Final drive
• Quattro drivetrain
• Electronic and mechanical configuration

If you provide your VIN, engine code, or original gearbox code, compatibility can be checked against the listing specifications.

Condition

Condition: Verify listing condition.

If sold as a used transmission, normal signs of previous use may be present, including surface marks, scratches, oxidation, or other cosmetic wear.

Before installation, the gearbox should be inspected for:

• Oil leaks
• Damaged housings
• Damaged mounting points
• Input/output shaft condition
• Flange condition
• Selector mechanism
• Bearing or gear noise
• Correct transmission oil level and specification

Please review the product photographs carefully and confirm what components are included with the gearbox.

Installation

Professional transmission installation is recommended.

When replacing the gearbox, the mechanic should verify compatibility with the existing:

• Clutch
• Flywheel
• Clutch hydraulics
• Driveshaft
• Front/rear differential
• Axles
• Gear selector
• Transmission mounts

After installation, the correct transmission fluid should be used according to the vehicle and gearbox specification. The transmission should also be checked for leaks and correct gear engagement before the vehicle is returned to service.
