Both the standard-wheelbase and extended long-wheelbase (Pullman) versions of the W220 are documented, covering body, chassis, and interior differences between the two configurations.
Are the 722.6 transmission rebuild procedures included?
Full rebuild coverage is provided for the 722.6 5-speed automatic, including torque converter, valve body disassembly, conductor plate replacement — a well-known failure point on these models — fluid specifications, and electronic control diagnostics.
