Ferrari Mailing List: Gearbox lubricants

[Charles G Perry IV (charles]

I'm sure this is hard to describe without actually experiencing it, but can 
someone describe in detail what exactly the chatter is and/or what it feels 
like in practice?

I'm having some continuing gearbox issues with my TR and after having had 
two good mechanics check it with minimal improvement, my next thought was to 
buy several different recommended oils and test each of them to see if any 
of them help, but aside from the smoothness in shifting I'm not sure what 
else to watch for to judge their performance.

Thanks!
