Buying & Market Guide
Because these are high-value exotic car parts, finding a “complete” gearbox involves verifying whether the unit includes the essential Transmission Control Unit (TCU) and internal sensors.
-
Availability: Units are primarily available as used/refurbished through specialized exotic recyclers or online platforms like eBay and Ovoko.
-
Condition: Most used gearboxes on the market are “take-offs” from low-mileage donor vehicles. It is critical to confirm the mileage
Technical Advisory
 Critical Replacement Info:
Programming: Installing a new or used 13GA004CP requires McLaren MDS (Diagnostic System) to perform a “Clutch Kiss Point” adaptation and gearbox software sync. It is rarely a simple “plug-and-play” swap.
Common Issues: Early 570S models sometimes experienced clutch seal leaks or pressure sensor failures. If you are buying a used unit, ask if the main seals have been inspected or replaced.
Maintenance: If you are servicing your existing unit, ensure you use the correct Pentosin FFL-4 fluid (or McLaren equivalent) and a new OEM Transmission Filter (approx. $290).
