DCT Valve Body Same Between F8X and E9X?

Need to replace my DCT Valve Body/Mechatronics.

Wanted to see if anyone knew if the valve body is the same between the F8X and E9X? Just the valve body swapping over the TCU. I see the part numbers are difference for the full mechatronics with TCU part numbers so wondering if the valve body might still be the same. I have found some different replacement valve bodies on eBay and most list that they work for E9X and F8X.

This is a remanufactured one I found on eBay that lists F8x and E9x. I'm waiting on a reply to see what exactly is involved in their remanufacturing process.

I also found a used valve body off of a m2 comp with only 47k miles that I feel might be a better bet.

Had the car a couple months now. Came with an issue where when fully warm hard jolt on 1st or Reverse gear. Troubleshooting I found fluid was only filled to cold fill level. I did a full flush with Pentosin, new filter, suction pump, and all that ISTA+ adaptions. It did help some but issue still persists. Plan is to change the valve body and clutch pack since ill have the transmission down. Don't think its the clutch pack since no slipping and hooks hard but might as well. While warming up and even in cold weather it will have no issues. 2011 E90 114k Miles
