Hey mate and sorry to hear that your having trouble with your gear box. I have to say the dealers here in WA are pretty average. Not sure who you are seeing at the moment out of Melvile Osbourne Park or Wangara, but generally Id say when you talk to them don't talk to the service reception guy ask to speak to the service manager (Carl is the guy at Osbourne Park) and get them to have a mechanic join the chat. the skips at least two of the steps. Once you get them to agree its not normal then push that if it not normal and the computer doesn't know whats wrong then they might have to do some old fashioned Mechanical work and pull it out and manually inspect it.
