Removed my shifter and the rubber gasket that has 6 metal spacers/ washers two are missing and presumed dropped into the tranny shifter hole. I actually put a small magnet down there and fished out 1 but 2 are still missing. There is no drain plug below the shifter so if I drain tranny oil will it drop the level there enough to see if the other two are in there? I got a new rubber seal with the spacers but dont want to install it if I have two metal spacers down there.... ugh, what to do
