Purpose and Specifications

FEBI BILSTEIN 38935 is a premium automatic transmission fluid (ATF) designed to keep your transmission running smoothly and efficiently. This 5-liter yellow fluid serves multiple critical functions: it lubricates internal transmission parts, maintains hydraulic pressure for gear shifts, and cleans deposits that build up over time.

This fluid meets strict manufacturer standards including Ford WSS-M2C938-A, Jaguar Fluid 8432, BMW ATF 2, and Shell M-1375.4 specifications. It works with a wide range of premium vehicles including BMW, Audi, Jaguar, Land Rover, Porsche, and Hyundai models.

• Thermal Stability: Resists breakdown at high temperatures, preventing sludge buildup that reduces transmission efficiency
• Corrosion Protection: Guards against rust and wear on internal metal components
• Low-Temperature Flow: Maintains smooth operation in cold climates without thickening
• Foam Prevention: Reduces air bubbles that can cause pressure loss and jerky shifts
• Extended Wear Protection: Keeps clutches, bearings, and valves clean and protected

When to Use / Replace?

Check your vehicle owner's manual for the exact replacement interval, as this varies by manufacturer. Most automatic transmissions require a fluid change every 60,000 to 100,000 kilometers (37,000 to 62,000 miles) or every 4 to 6 years, whichever comes first. Some modern vehicles with sealed transmissions may go longer between services.

Replace your transmission fluid immediately if you notice: dark or burnt-smelling fluid, delayed gear engagement, rough or jerky shifts, or transmission slipping. Old fluid loses its protective properties and can cause expensive internal damage.

This product comes in a 5-liter canister, which is typically sufficient for a complete fluid change on most vehicles (check your manual—some require 6 to 8 liters total). Store in a cool, dry place away from direct sunlight.

Frequently Asked Questions

Q: Can I mix this fluid with my current transmission fluid?
A: No. Always drain the old fluid completely before adding FEBI BILSTEIN 38935. Mixing different fluid types can reduce protection and cause transmission problems.

Q: Will this fluid work in my specific vehicle?
A: This fluid is approved for BMW, Audi, Jaguar, Land Rover, Porsche, Hyundai, and other premium brands. Check the compatibility list or consult your owner's manual to confirm your exact model and year are supported.

Q: How do I know if my transmission fluid needs changing?
A: Check your fluid color and smell. Fresh fluid is bright yellow or red. Dark brown or black fluid with a burnt smell indicates it needs replacement. Many vehicles have a transmission fluid dipstick or electronic level indicator for easy checking.
