Exclamation 2nd gen gearbox whine

I own a 2008 Mazda 6 2.0 ts2 with 65k on the clock. The car has recently started making a funny low pitched whinning sort of like sound when decelerating in almost all then gears but mainly noticeable in gear 3 and 4. The sound seems to be more audible on low revs say below 2000rpm and only when the throttle is off and the car decelerating on its own..the sound seems to be coming from the gearbox because if you depress the clutch whilst the car is in motion it will immediately disappear. On high speeds the sound is not audible at all. The funny thing is all gears engage in without any problems, the car drives very fine. Sometimes that sound doesn't happen at all, its intermittent. I tried changing the mtx oil but did not solve the issue, gearbox still whinnes. Could it be some bearings in the gearbox? Can they fail at 65000 miles? Should i be worried about it? Have been driving it like that for the past 6k miles. Had forgotten to mention that this started after changing engine mounts. Not sure if its related to that or not
