Does any one have a pic of the mod i need to do for the pressure regulator valve on the 2004R? I need to know what to grind off of it. I know how to take it out and all of that stuff. thanks guys!
Small land between the holes. Towards the bottom. Gring two flats and deburr. Not real critical. Do you know why you are doing this mod? It is to help converter life by feeding oil differently. It also helps stabilize pr valve to an extent.

im doing it because its buzzing and ive heard from many people that its probably the p.r. valve. I got the car from my uncle about 2 mohnths ago and he said it was doing it for a while before he gave it to me. Does this buzzing hurt the tranny in any way?
