Issue subsequent to the lower gearbox

Greetings I am experiencing an issue with the replacement of the ZF8HP automatic gearbox on a 2012 BMW F30 320d with 184 miles. I am experiencing a CD94EC error, and the vehicle jerks during rapid acceleration. Do you own a solution to this issue? Thank you so much for your response.

If the gearbox is not original to the vehicle, it likely requires coding to the automobile. Uncertain if ISTA will suffice or whether an alternative is required. Require a somebody with more expertise in coding to contribute.

You have already addressed that question in your first article.
Any modifications of such kind need coding, since all components are programmed to the vehicle, and each module has a serial number that must be altered, even if the part is identical.
