"Buzzing" sound when accelerating in OD
Hey guys,
When in OD, if I get on the gas to accelerate (but not enough to kick down), I hear a pretty loud buzzing sound coming from the transmission (or that's where it sounds like it's coming from). I can also feel it in the gas pedal. It almost sounds like how a hydraulic pressure relief valve sounds. If I turn OD off, it doesn't do it.
Anybody ever experienced this?
Thx,
-Dave

My 04 does the same thing when the engine is "lugging" in OD. I believe it to be one of the heat shields on the exhaust rattling or buzzing when the engine hits the sweet spot. I did have the dealer check it several times, they of course couldn't duplicate the problem, so they never corrected it.

It does sound like the heat sheild. I had it on my old truck. When I traded out my exhaust the sound when away.

Thanks for the replies guys. I hope it's just something lose rattling but I'm doubtful that's it. It's only in OD and it's very high frequency. I'll crawl around underneath and see if I can find anything. The steel wool idea is a good one.

Old post I know but life gets in the way sometimes. I'm still having this issue. I didn't find any source of sheet metal vibration. I really think it's coming from the transmission.
Thoughts?
Thanks,
