So I have a question? While I’m driving through town doing the speed limit around 45, 50 or so after, My truck has shifted through all its gears I come to hill and you know slightly giving it some gas just enough gas to where it doesn’t shift down. I hear like some valve tapping or kinda sounds like a standard truck does when you need to shift down to get power. But it comes from the valves at least I think it does. I was wondering if that was normal my truck only has 13,000 miles on it. Got it brand new And I love it. First time having a tundra I love the power of it and the torque. I also feel like this is normal because it’s a big block.
