2013 35i E70 8 speed Transmission question....

[HtownBlue]

Does anyone know the part numbers or possibly a link for the correct Mechatronic valve seals needed for the 8 speed transmission?
I can only seem to find those which are perfectly cylindrical and those with the “scoop” at the end. I want to make sure I purchase the correct set along with the other seals etc. etc. when I do the service. Thanks for any responses.

I recently did this to mine along with replacing all the solenoids (150K miles on it). There is only one true mechatronic sleeve for the ZF8HP that goes between the valvebody and transmission (B release). It is incredibly hard to find and the only place I was able to get mine was off of Ebay. Below is a link, takes about 7-10 days to arrive from the netherlands. Comes with two other mechatronic seals that you might as well replace while you are in there.

Thank you for the feedback friend. Great find on the seal kit.

Did this make a big/noticeable difference in your shift quality? My E70 has 130k miles on it and I've done the fluid and filter change, but it still doesn't shift that great. I particularly hate the 1-2 shift.
