For sure 7/10. Just to note, I have never replaced a transmission before. Im just an at home wrencher. Did it on jack stands. Most difficult part was lining up the trans back into the motor.

- My car wasnt high enough so I jacked the car up higher and pulled it through the front.

Everything else not too bad. New cooler lines since the ZF is longer and had a different hold down. re pin the mechatronics connector and thats it. Dont need to flash your vin to the car.

Make sure to reset engine adaptations and rest taught values for the transmission so that they get used to what your car has. the rest on the trans isnt resetting the adaptions but more of resetting the driving style. I have ACC so the trans will learn how to drive with that module in.

I made a more in depth post here https://www.reddit.com/r/E90/comment...zf_6hp21_swap/
