Hey guys, My truck is making a very odd sound. When my truck is accelerating directly after a gear change when a load is applied I get a really odd tin can retelling noise. Sounds like someone is shakng a bag of soup cans together. This comes out as soon as I pull off the cutch to let the gear pull. It can also be heard if I rev the engine at idle. At the low rpm range the rattle persists. Also seems to have slightly less pulling power in the gears. Also noticed that my temp guage has gotten a little warmer than it usually is. I was thinking something might be stuck in the Converter (if these trucks have them) or exhaust in general.

Thanks,
