Yup, there is a small seal that surrounds the rod going in and out of the console. It is standard in all of the seal kits and you may be able to get one by itself if you call GPRparts.com and talk to Dave. To change it out you need to:
1) Remover shift console from tranz (2 13mm nuts and some whiggling after you have removed the sift linkage)
2) Drive one of the roll pins (doesnt matter what side) out of one end
3) Remove rod from console and you will see a seal on the outside port.
Removing the seal is a PITA at times. Just be careful not to score the bushing inside the console that the rod rides in, or the seal surface.
If you do not want to do this yourself, you can send me the console and I will do it for you
