Hello, long time lurker/leaver/justcame back for help



Recently when I start my truck, (2000 1500 4x4) I get this rattle in the (i think) transmission about 5 seconds after I start the truck and then it goes away after 3 seconds. I makes this noise no matter if it is in park, reverse, moving forward, etc. Just when I first start it. I fell no performance issues, it shifts fine, drives fine, just a loud rattle when starting up, then it smooths out. the only time i can make the sound change is if I change the shifter for the 4x4, but it still does not go completely away. If I rev the engine at first start it waits untli the rps drop back down and then it does the rattle.



any clues? thanks

If the noise alters with the 4wd lever, check the linkage to the transfer case. Otherwise, my first thought is also the cat converter shield or the cat itself.

yes, I accidentally found out today it was definately coming from the exaust somehwere. was cleaning the chrome pipes and i heard the rattle. maybe not the cat but somewhere along that line.

I think when 4wd was engaged the vibration was just different, so it did not rattle as much.

thanks!

If it's coming from the exhaust, then it is either the cat or the shield.
