On my 81 300D the trany is leaking out of what looks like where the dipstick attaches to the trany. There is a couple of crush washers, I'm assuming, that I should replace? Where would I get these washers at? I didn't want to take it off and have all my fluid leak out and not be able to find it anywhere. I live on an island and there is currently no dealership here, it's being rebuilt. Where is the best place to get them? Anyone happen to know exactly what size spec? Thanks Aloha
