I see that this thread is quite old, but great work Nicene!
I just noticed this week that there is a "whirring" or "ticking" sound coming from second gear on my '05 speedy.
The engine has nearly 60k miles and I definitely kick the shit out of second gear. Lots of time in NYC traffic, lots, and lots of clutch up wheelies.
No catastrophic failure like yours, yet, but I'm thinking that sooner or later i'm going to have to split the cases and assess whatever damage is causing that sound/feeling in second.
Not happy about it, but it's nice to see that one of us mortals can actually get through this job.
