Odd Transmission Noise -Yukon Hybrid - any thoughts?

[jimmystartup]

I've been noticing an odd noise that seems to be coming from the transmission. It happens around 1900 RPM when accelerating from a stop or rolling stop. I don't know much about transmissions so I can't explain where the noise is coming from but it sounds a bit like the transmission is in between gears and grinding a bit before finally moving up a gear and settling down.

This is a 2008 Yukon Hybrid with 32,000 miles and I figured I'd ask if this is unusual before taking it into the dealer and having them listen. I don't want to experience the old "can not duplicate customer complaint" syndrome.

Take a video camera and record and put it right on the steering column. Hopefully you can capture the noise and approximately at what rpm range so you can show that it isn't a "can not duplicate" situation. You will have proof.

Ooh, good idea. I was looking for a reason to buy one of these - Go Pro Camera and this might be the perfect time.

Thanks.
