Well atleast I think it's the tranny making the noise.

When towing over the weekend, I heard it. Going up hill, 2 gear pulling fine, I started hearing a rattling noise. Sounds like popcorn shaking around in a plastic bag. Pretty strange.

I got under there and checked all the bolts and mounts. Nothing. This weekend I planned on changing the tranny fluid and filter, maybe that will give me some insight.

Anybody have any other suggestions?? Thanks!
