BMW E series and F series vehicles equipped with the ZF 6HP/8HP transmissions, and the EWS4 system (starting with the E70, X5), the transmission control module (Mechatronic) is mated with the DME, CAS/FEM modules for the specific vehicle. When a transmission replacement is required, it is not possible to install a used automatic transmission without affecting the ability of the vehicle to function.

The EWS 4 system will prevent gear selection due to “non-matching” rolling code in the control modules, it is a security function.

Your options were buy a new transmission from BMW, 7k plus or part out the vehicle if original mechatronics is damaged.

Send us your CAS/FEM, working key and your new/used mechatronics module and we and we will matched it to your vehicle. 8HP can also be made into a virgin for future use. DCT matching is also available.
