E85/E86 Z4 (2003–2008): 6-speed manual (ZF S6-37BZ) or 5-speed automatic (ZF 5HP19). E89 Z4 (2009–2016): 6-speed manual or 7-speed DCT (GS7D36SG / M-DCT). G29 Z4 (2019+): 8-speed automatic (ZF 8HP51) on sDrive30i/M40i; 6-speed manual on M40i. All Z4 are RWD.
The Z4 is a sports car — transmissions are often worked harder than in sedans and crossovers. Track use on M-DCT models accelerates clutch wear significantly. The G29 Z4 8HP51 follows standard ZF 8HP procedures.
M-DCT uses BMW MTF LT-5. 5HP19 uses ZF LGF5. 8HP51 uses ZF LGF8. Manual transmissions use BMW MTF-LT2.
M-DCT service: 3–4 days. 8HP51 rebuild: 3–4 days. Manual synchro: 3–4 days.
