Product Information
Full details
Carlube DCT-U is a high-performance, fully synthetic lubricant engineered for automotive technicians and vehicle owners looking to maintain consistent launch and anti-shudder performance in wet-clutch transmission systems. It simplifies maintenance by replacing the need for multiple manufacturer-specific fluids across major European and Asian brands; however, it is strictly formulated for wet-clutch systems and must not be used in dry DCT applications.

FAQs
Can I use Carlube DCT-U in a dry DCT?
No. This fluid is formulated specifically for wet-clutch transmissions. Using it in a dry DCT will cause damage to the clutch components.
Which vehicle manufacturers are supported?
It is compatible with a wide range of manufacturers including Audi, VW, BMW, Peugeot, Citroen, Ford, Mercedes-Benz, Mitsubishi, Nissan, Porsche, and Volvo.
Is this a fully synthetic lubricant?
Yes, Carlube DCT-U is a fully synthetic lubricant designed for high thermal stability and oxidation resistance.
Does this fluid protect against rust?
Yes, it contains specialized anti-corrosion and anti-rust additives to protect internal transmission components.
How often should I change this fluid?
Always follow the transmission fluid service interval recommended by your vehicle manufacturer in the service manual.
Troubleshooting
Noticeable shuddering during low-speed gear engagement
Verify that the transmission fluid level is correct and ensure the vehicle uses a wet-clutch system; consider a full fluid flush if the old fluid was heavily degraded.
Difficulty shifting after fluid change
Check that the correct fill procedure was followed and that no air bubbles are trapped within the mechatronic unit.
Pros and Cons
Pros
- Reduces inventory costs by consolidating multiple manufacturer-specific fluids
- Fully synthetic base ensures longer service intervals and thermal stability
- Provides smooth gear shifts by optimizing friction characteristics
- Trusted UK-based manufacturing quality standards
- Excellent anti-corrosion and rust protection properties
Cons
- Completely unsuitable for dry dual-clutch transmission systems
- Requires professional knowledge for proper transmission flush and fill procedures
- Not intended for traditional automatic transmissions or manual gearboxes
Setup, Compatibility & Care
Before installation, always consult your vehicle's owner manual or service handbook to confirm the transmission is a wet-clutch DCT. Using this fluid in a dry DCT system can lead to severe mechanical failure. During the change process, ensure that the transmission is at the correct temperature range as specified by the manufacturer and use the proper fluid level measurement tool. Because this is a sensitive hydraulic system, perform the fluid change in a clean environment to avoid debris contamination. Store the remaining fluid in a cool, dry place with the cap tightly sealed to prevent moisture absorption.
