Road tests by R&T and M/T say nothing about gearbox differences-just faster shifting and a 6% shorter final drive.
Go to Eurospare's online parts catalog and check to see. May take you a while. Many of the parts in the GTO gearbox are shared with the 575M through GTO, and even the Enzo, but some digging should show you the differences. Post what you find.
As you know GTO shifts in 60 or 80 msec. Is it because of the TCU differences or other mechanical changes were done?
Changes were made to the F1 hydraulics, TCU software, and supposedly gearbox for Superfast II, with 60 ms min shift time, same as the Scuderia/16M. The HGTE was already down to around 85 ms.
