Light Humming Noise?

[carter1551]

I posted a while back about this but now Ive got more detail on it. I notice a humming that seems to be coming from the engine or transmission. It only happens when i am going around 25mph and im in 2nd gear and the rpms read about 1500. It also seems more obvious if im coasting around 25 and 1500 rpms rather than throttle down and running at 25mpg and 1500rpms Dont know if i should be worried about this or not.

auto tranny? that humming is normal. there is a TSB out on it, something with the harmonic balance or whatever. nothing to worry about

Excuse me but what is a TSB?

Technical Service Bulletin. They are issued by the manufacturer for certified techs to reference for common problems. A TSB is NOT a recall, as some people get them confused.
