Thank you, I agree, the 8HP is an awesome trans. My only complaint is that BMW chose the weakest version for the 535. The 8HP70 that is used in the 550 is also used in things like Dodge Trucks (including diesels), so if it can handle the torque demands of a diesel, it should surely be capable of a modded 535. Then the only upgrade would be an 8HP90 - which is the trans used in the Dodge Challenger Hellcat. That would be fun, but I seriously doubt the N55 will ever be developed enough to generate the 740 lb ft of torque that trans is rated at.
