Lawn tractor noise automatic trans
 

My neighbor just bought a new Deere Lawn tractor. But he says that there is
a slight noise, like a metalsish noise, comming from it when he starts to
move the automatic transmission level foward or backwards. He says he didnt
have it on the other 6 speed tractor he just got rid of.

Is this normal?

hydro's tend to make awhining noise
