Caveats and conflicts (2)

Chart is the only source opened. Spec B gearbox is a TY856 6-speed with viscous center diff and 0.891/0.707 5th/6th (different ratios from STI).
Chart codes are market specific; US/CA codes used. JDM and EU codes differ (e.g. TY856UB1KA JP STI MY08-14, TY856UG1MA EU). Subaru parts catalog (parts.subaru.com) is Cloudflare-blocked so no OEM catalog confirmation.
