McLaren 600LT Gearbox (13GA015RP) is the ultra-high-performance 7-speed Seamless Shift Gearbox (SSG) tailored for the track-focused Longtail series. This transmission is a evolution of the unit found in the 570S, specifically tuned to handle the increased power of the 600LT and provide even faster shift times.

Transmission Overview & Specs

The 13GA015RP is a dual-clutch transmission (DCT) produced by Graziano. It is renowned for its “Inertia Push” technology, which utilizes the engine’s built-in inertia to deliver a burst of torque during upshifts, creating a seamless and incredibly rapid acceleration curve.

• Model Type: 7-Speed Dual-Clutch (SSG)

• Part Number: 13GA015RP

• Compatibility: Specifically designed for the McLaren 600LT Coupe and Spider.

Technical & Buying Advisory

Sourcing a gearbox for a Longtail McLaren is a high-stakes purchase. Ensure you are looking for a unit that is verified for the 600LT, as the software and clutch calibrations differ from the standard 570S units.

• Condition Check: If buying used, verify the donor VIN and mileage. Look for units with less than 15,000 km to ensure longevity.

• Installation & Coding: This gearbox is not plug-and-play. It requires the McLaren Diagnostic System (MDS) for clutch “Kiss Point” calibration and TCU (Transmission Control Unit) synchronization.
