So I have a 2019 Adventure, I am the first owner and it has 18,000 miles. I've noticed that when driving at low speeds, I can hear an audible click when the trans shifts either up or down (I'd say it typically happens between 1st and 3rd gear). This by all means doesn't seem normal. I took it to Toyota and mentioned it to them and they immediately thought that it was the rear diff and transfer case TSB. So, I've had both of those done, but the clicking noise is still there. Has anyone else heard this sound, is this normal? I hope not because it seems like whatever is making the sound is going to wear out quick.
