Gents,
As I had described earlier in a post, I've had the same problem but mine was in 1st gear as I slow release my clutch from a dead stop. The clutch would pop out with a loud bang and vibration on the shifter that would seem jarring. So I took it into the dealership and had warranty work done on it.
Solution:
The technician found that the manf. had setup the 1st and 2nd gear syncros at the very edge of the specs and with natural wear and tear of the syncros, the gear was slipping due to the OEM setup being at the edge of the specs. So... he replaced my 2nd gear syncro which he says affected my 1st gear problem. By replacing only the 2nd gear syncro, he was able to solve the problem.
Hope this helps.
