BMW M Transmission Tuning: DCT vs ZF 8HP — Two Systems, One Goal BMW's M division has used two fundamentally different automatic transmission architectures across its modern lineup: the GS7D36SG dual-clutch transmission (DCT) in the F8x generation, and the ZF 8HP torque-converter automatic in the G8x generation and F90 M5.

If you're running a Stage 2 ECU tune on any BMW M car, your transmission calibration needs to keep up. Factory...

For the first time, BMW's flagship performance sedan pairs a twin-turbocharged V8 with an electric motor, creating a plug-in hybrid powertrain that produces a combined 727 HP and 738 lb-ft of torque.
