Info on F30 335i 6MT transmission/upgrades
I recently picked up a 2015 335i M Sport with the 6MT. I'm fairly sure this is the ZF S6-53 but I could be wrong. I was just wondering the capabilities and limits of the stock form of this transmission in terms of future engine mods. Also, if I were to need to upgrade it to hold more power in the future, where should I look for stuff of that nature?
