Well when i'm in gear and i'm strolling (without accelerating) it sounds like my tranny is grinding, but when I hit the gas it stops.

A mechanic told me it's not anything major, besides a bearing being loose or something?

It's been like this for awhile and I haven't had any problems, but just curious what is causing this.

 

i have the same problem as you. the bearing is loose. nothing major just annoying. haha
