A Quick Tech Note for Accuracy: When sourcing a replacement N54 or planning a transmission swap, verifying your crankshaft bolt pattern is absolutely essential. BMW utilized an 8-bolt crank design in early production models (typically built up to January 2009) before transitioning to this stronger 6-bolt crankshaft design for the remainder of the N54 production run. Ensure your flywheel or torque converter matches this 6-bolt configuration for a seamless, trouble-free installation.
