Offroad-Express

its v6 surf auto transmission

it makes whistling sounds on the first few seconds when i put my foot down on accelerator

this almostsounds like wind drafting through a hole

where should i look first?

hi check ALL vaccum lines for leaks

i had this exact same problem on my 1kz powered surf, it turned out to be the rear exhaust manifold stud had loosened and the exhaust gasses passing though the steel gasket made it whistle, really loud too, loud enough i couldnt drown it out with the factory stereo
