McLaren 600 LT Transmission Automatic 13GA015RP

McLaren 600LT Automatic Transmission (7-speed Dual-Clutch / SSG) with the part number 13GA015RP involves sourcing a highly specialized gearbox designed for the “Longtail” performance envelope. This unit is part of the P13 platform but features specific software and hardware tuning to handle the 600LT’s increased power and faster shift requirements.

Technical Breakdown: 13GA015RP

This part number refers to the Seamless Shift Gearbox (SSG) assembly, which is a Graziano-manufactured dual-clutch transmission.

• Type: 7-Speed Dual-Clutch (SSG).

• Application: Specifically optimized for the 600LT Coupe and Spider.

• Key Feature: Features “Inertia Push” technology and ultra-fast gear changes (faster than the standard 570S).

• The “RP” Suffix: In McLaren parts nomenclature, “RP” often indicates a Remanufactured or Service Replacement part, often provided as an exchange unit through McLaren retailers.

Buying & Installation Advice

• Software Sync: You cannot simply “plug and play” this gearbox. It must be paired to the vehicle’s ECU and TCU using the McLaren Diagnostic System (MDS) to perform a clutch “Kiss Point” adaptation and gear position calibration.

• Oil & Fluids: Requires Pentosin FFL-4. It is highly recommended to install a new gearbox oil filter (11G0521CP) at the same time.

• Condition Check: If buying a used unit, check for “seepage” around the hydraulic actuators. These are the most common failure points in the Graziano units.
