So I was going to check/replace fluid in the T-5 since I had the car up and I am not sure what the PO did and it whines pretty good. More than likely needs to be rebuilt but want to make sure it has fluid in it. HOWEVER, I can't get the damn fill plug out. I have a pretty long torque wrench and can't get the top fill plug to budge. I don't want to break/strip anything. I figure if I start with the fill plug and give up nothing lost. So do these things seize up or what? And what are the risks of more torque on it?
