dct transmission noise

[qhdrnf4]

Hello I am the owner of the E89 Z4 35I residing in Korea. I am having a lot of trouble with a transmission problem recently. This was not properly repaired in Korea, so I came here.

My car's transmission is noisy for odd shifts when cold

Among them, the loudest transmission noise is between 3000rpm and 5000rpm.

There is no problem at all when shifting to even means after that.

Please provide an address if there is a post about this shorthand

I posted a video on my personal YouTube. If you have experienced this, please give me information. Please.

If necessary, you can send a longer video

Recent repair history is engine rebuild and head deformation repair.

Change main bearings can help you. I made it last year with my dct, no problems now. Bearings can be found at parts shops. Also, dct have problems with clutch cover, it unscrew and need to be modifed with screw-glue.
