When I was first considering the 08 Tundra I read something about the rumble strip, a problem with the torque converter. Yesterday when I drove my new truck, 08 Tundra, 5.7 4 wd, crew cab, I stepped on the gas and felt something strange as it shifted. I thought I had run over something. It only happens when rolling at about 45 mph and you gas it. Could this be the dreaded rumble strip? I put the words in the search and didn't come up with anything. I thought the problem had been corrected in the 08.
