bogging

Hey Guys, hopefully someone can help me so i can get this fixed - current issue: My truck is slow to accelerate in gears 3 to 5 when i hit the gas hard. Here is a quick background. i took it in a week ago because i was noticing some grinding/rattling from the exhaust and shifting issues...

Hey guys, First timer here. I have an '06 hemi 4x4. When i step on the gas from a stop it revs to about 2000 rpm and barely moves anywhere. I guesse what it feels like is its starting out in 2nd or 3rd gear, but with lots of rpms. feel free to ask more questions to diagnose the problem...
