Got a used Mercedes transmission that won't move? In a Mercedes-Benz, the transmission is "married" to the original car’s security system. If you swap in a used unit, it stays locked to the donor vehicle, leaving your car stranded. At ClusterFix Texas, we provide the "Best of Both Worlds" solution: we set your used TCU back to its factory "Virgin" state, allowing you to bypass the dealership’s expensive replacement costs and use the transmission you already have.

The Experiential Truth of a Seamless Swap

Imagine the satisfaction of turning the key and feeling your Mercedes glide into gear with a transmission that costs thousands less than a new one. By "virginizing" the conductor plate, we release the electronic lock. Once you receive the unit back at your shop in Houston, Dallas, or right here in San Marcos, you can initialize it to your car as if it were a brand-new factory part.

HOW IT WORKS (The Shipping Checklist)

1. Verification: We support VGS, VGS.2, and VGS.3 versions (including part numbers starting with A033, A003, etc.). Check the compatibility list below. If you aren't sure, text a photo of your TCU to (512) 792-1717.

2. Prepare the Part: Remove the TCU (Conductor Plate) from the valve body. Important: Send the TCU only—do not ship the heavy valve body (refer to the listing image).

3. The Paperwork: Print and complete our [Disclaimer Form HERE]. Include:

• Your Name, Phone, and Return Address.

• Vehicle Year, Make, Model, and VIN.

4. Secure Shipping: Pack the TCU with extreme care. These units are delicate—use at least 6 inches of padding.
