dumb question.. is it the doors locking?
Metallic clanking noise when going 1st to 2nd while cold
2007 Metallic clanking noise when going 1st to 2nd while cold
I have a new 2007 Tundra DoubleCab 5.7 L V8. It has 800 miles on it and runs like a dream. When the truck hasn't been used for an hour or more and I first start it up there is no unusual noise. When I move it into drive and give it some gas it goes through 1st gear just fine. When it shifts to 2nd gear around 15 mph I hear a brief metallic clanking noise which sounds like it is coming from under the front half of the truck, possibly up between the front wheels but it is hard to tell. I suspect it is in the center of the vehicle since my wife said it sounds like it is on my side and to me it sounds like it is on her side. After this noise the truck runs and shifts great and the noise never recurs even when stopping / starting out from red lights, slow or fast acceleration, manual shifting, etc. If I turn the truck off briefly in park and restart it still doesn't seem to do it, but it if I let it sit for some time (seems like an hour or so) then it happens again. I first thought maybe it is from the engine or transmission being physically cold but sometimes the water and transmission gauges still show some heat on them when I start up and it happens again. This could be a normal noise but it sure doesn't sound normal. I have it in 2WD the entire time. Any ideas before I run it back down to the dealer in a panic and waste another day of vacation time for something that could turn out to be nothing?

No, I changed the doors to lock when taking it out of park, and thankfully I am not that clueless but thanks for checking. It was a good guess based on the speed but only for total tools, which hopefully will be driving Fords and GM instead of Tundras...
Actually, I test drove a new Tundra and heared the same noise. My 4Runner makes this same noise but it comes from the front dash area firewall side. Its the traction control gizmos firing up
