Not another 3650 issue!

Hi All,

Hope everyone had a good holiday and didn't pig out too much :)

I drove from Seattle to Portland and back this weekend and after the car sat over night on the trip down in quite cold temps 29 ish when I drove off somewhere the next day I notice a rather loud clinking sound almost like something is loose in the gearbox only in 5th gear while the car is cold.

Since the 3650 2nd gr grind TSB done 5th gear has been a bit noisy but not like that. It almost sounds like a synco is loose or something very odd.

any comments welcome?
