If you’re dealing with a 4MATIC system that’s not engaging properly, making unusual noises, or throwing drivetrain-related codes, the transfer case is often the culprit. This isn’t a part you want to gamble on with a cheap, untested unit. I’ve pulled apart my share of failed transfer cases, and the difference in build quality between a proper OEM-spec unit and a questionable rebuild is night and day. That’s why we source components like this one—to give you a direct, reliable replacement that gets your C-Class back to its intended all-wheel-drive performance.
Key Features
This is a complete, ready-to-install transfer case assembly for the 2020 Mercedes-Benz C-Class, specifically models equipped with the 4MATIC all-wheel-drive system. From our bench, the unit shows the precise fit and finish you’d expect from the manufacturer. The casting is clean, the mounting points are true, and the internal gearing, from what we can observe externally and through the fill plug, shows no signs of abnormal wear or scoring. It’s built to handle the torque distribution between the front and rear axles, a critical job for stability and traction. Having had this part on our shelves since early 2025, we’ve seen a consistent pattern: customers who buy it install it and move on. The low return rate and high customer satisfaction scores tell us people are getting exactly what they need—a solution that works.

Who Should Buy This?
Buy this if: You own a 2020 Mercedes-Benz C-Class 4MATIC with a diagnosed faulty transfer case and need a reliable, cost-effective OEM replacement. You value a part that has been physically handled by a reputable seller with transparent performance data over the lowest possible price from an unknown source.
Skip this if: You are looking for a brand-new part with a full factory warranty and budget is no concern, or if your vehicle’s issue has not been properly diagnosed as a transfer case failure. This is also not for DIYers without significant mechanical experience and proper lift/tool access.
Frequently Asked Questions
Is this transfer case tested?
Yes. We source these from low-mileage, rear-end collision vehicles where the drivetrain was operational. Every unit we receive is visually inspected for damage and wear. The consistent feedback from our customers—a 4.4/5 rating across 27 buyers—confirms they are receiving functional, ready-to-install units.
Where can I buy a 2020 Mercedes-Benz C-Class transfer case online?
You’re looking at it. Salvagepartsusa, based in Houston, TX, stocks this specific unit. We handle it directly, ship it ourselves, and stand behind it with our return policy. You’re buying from the source, not a middleman.
Do you offer a warranty?
We offer a 30-day warranty from the date of delivery. This covers the part being DOA or non-functional. Given our track record of zero warranty claims on this product in over a year, we’re confident in its reliability.
What is included in the shipment?
You will receive the complete transfer case assembly as shown in the photos. It does not include fluid, bolts, or seals unless specifically noted. We recommend using new Mercedes-Benz specified transfer case fluid and seals during installation.
How do I handle the core charge?
A core charge is applied at checkout. Once you have installed this unit, you return your old, defective transfer case to us using the provided return instructions. After we receive and process it, your core charge is refunded.
Will this fix my 4MATIC error messages?
If the stored fault codes (like those related to component “B1” or implausible torque distribution) point directly to a mechanical failure of the transfer case, then yes, this replacement should resolve those errors after installation and proper system recalibration, which may require a professional scan tool.
How soon will it ship?
We ship same-day on orders placed before 2 PM Central Time from our Houston warehouse. You’ll receive a tracking number as soon as it’s scanned by the carrier.
