BMW ZF 6HP/8HP Transmission Swap Matching



BMW’s 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 modules for the specific VIN number. 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 scrap the car.

Bring us your vehicle with your new/used transmission and let us mate it to the vehicle. Currently this service is only available at our location.

Shops are always welcomed
