Been looking at getting a Z4 with DCT do use as a daily driver
I?ve noticed that the DCT on the Z for Park indicator and seems to function the same way a normal automatic does On BMW and M models there is no park, is what?s in the Z4 really a DCT I have seen much made of how DCT doesn?t have a park feature yet the Z4 does Seems seems to apply to the 135I |

I think its because of different style of gear lever in the M3 that functions differently.
And how its coded. Note that in the m3 DCT does not shift up and stays at the revv limiter. In Z4 it shifts to the next gear. Also in Z4 you cant control the harshness of the shifts individually like in the m3. its done with the normal/sport/sport+ button programs together with engine , steering and adaptive suspension. Found this on M3post(how it functions in M3): Quote:
Gearbox is said to be the same GS7D36SG unit in both but have to note that DCT in Z4 and DCT in e90 M3 have different product codes so there are probably some differences like connection to the engine, thermostat, cooling, mechatronics unit ETC. But ultimately its the programming that determines how the box behaves. F10 M5 and F80 m3 have similar GS7D36BG gearbox that has bigger torque rating. And i remember Getrag who makes these DCT-s had two product codes for these DCTs... 7DC1600 and 7DC1700. 7DC1600 in e90m3, Z4 , some 335i 7DC1700 in F10 and F80 M cars. Its all the same DCT family.
