The conical torque ratio on the 5 speed is 15/30 - 1/2, on the first 2012 the oblique toothing made a tooth overlap of 1 1/2, later with the larger teeth the overlap of a single tooth was can cause more noise, the problem is if you are too meticulous and you put a marker on the teeth to see the correct support of the torque's teeth, you quickly realize that this does not always support the same right on the toothing of the toothed crown, the cause is bad machining.

I reassure you if you have a 365 GTB 4 BB or similar mechanically it is not better machined and in addition the teeth break frequently.
