modz 149 Report post Posted January 7 Been offered a very tidy and worked E91 335i. Great spec, ticks all the boxes except it is the 6HP auto box. I've done a lot of research into the 8HP box with the likes of Turbolamik etc but as it's going into a model that had the DCT box post 2011 (?) I wonder what else is required to 'factory swap' it - ie. no aftermarket parts, all OEM. 6 speed ZF GA6HP19Z box in the car currently. I'm fine to get the parts and do the wrench work, the TCU / electronics are the hard part for me Quote Share this post Link to post Share on other sites

exextatic 138 Report post Posted January 8 Definitely consider the CANTCU route if you're intending to use the vehicle as a road car / daily. 2 Quote Share this post Link to post Share on other sites
