BMW M2 COMPETITION F87 LCI GS7D36SG 7853560 automatic transmission
Part Number: 7853560 (Interchangeable with 8624172)
Model Code: GS7D36SG (7-Speed Dual-Clutch Transmission)
The GS7D36SG is the high-performance 7-speed M-DCT (Dual-Clutch Transmission) manufactured by Getrag for BMW’s M Division. This specific variant is optimized for the S55 engine found in the M2 Competition (F87 LCI). Unlike the standard 2 Series automatic, the M-DCT uses two separate clutches—one for even gears and one for odd—allowing for lightning-fast gear changes without any interruption in power delivery.
Technical Specifications
-
Compatibility: * BMW M2 Competition (F87): 2019–2021
-
BMW M3 (F80): 2014–2018
-
BMW M4 (F82): 2014–2020
-
-
Torque Rating: Rated for a maximum input torque of 700 Nm (516 lb-ft).
-
Clutch Type: Dual Wet-Clutch (Multi-plate).
-
Gear Ratios: Optimized for high-revving performance, with a very short 1st gear for rapid launches and a long 7th gear for highway efficiency.
Key Performance Features
-
Drivelogic: The M-DCT features the Drivelogic system, allowing the driver to choose between three shifting programs: Comfort (smooth, early shifts), Sport (faster, higher RPM), and Track (aggressive, instant shifts with “shift-lock” capability for drifting).
-
Launch Control: Integrated software that manages engine RPM and clutch engagement for maximum acceleration from a standstill.
-
Integrated Oil Cooling: The “SG” variant features an enhanced thermal management system, utilizing a dedicated heat exchanger to keep the hydraulic fluid stable during high-$G$ maneuvers.
-
Low-Speed Assistant: Features a specialized creep-mode logic to assist with parking and heavy traffic, though it maintains the mechanical “bite” characteristic of a manual gearbox.
Technical Installation & Cataloging Notes
As a highly complex mechatronic unit, the GS7D36SG requires specific technical procedures during installation:
-
Drivelogic Calibration: After installation, the transmission must undergo a “Clutch Teach-in” procedure via BMW ISTA. This allows the DKG (Dual-Clutch) Control Module to learn the exact kiss-points of the clutch plates for smooth operation.
-
Fluid Requirements: This unit requires BMW Pentosin FFL-4 (DCTF-1) fluid. It is critical to use the correct specification, as the hydraulic actuators and clutch friction material are sensitive to the oil’s viscosity and additive package.
-
Oil Pan Integrity: The plastic oil pan on the GS7D36SG is prone to seepage over time. For “As New” inventory, it is recommended to inspect the pan and gasket, or upgrade to a billet aluminum pan for improved cooling and durability.
-
Software Synchronization: The transmission is VIN-locked to the vehicle’s EWS (Immobilizer system). A used transmission must be “reset” or “virginized” before it can be coded to a new vehicle to allow it to shift out of Park.
