I checked with a mirror and a flashlight today and its the shifter seal. I was just planning on change all the seal on the primary but are you suggesting I change the tranny seal at the same time...how difficult are they to remove.

I have replaced those seals on two bikes in the last two weeks. Removing the seals is easy. Getting to them is a little harder.
You have to remove the outer primary, the primary drive train and the inner primary. Compensator has right hand threads and the clutch basket nut has left hand threads.
You have to remove the two screws that fasten the starter to the transmission and primary. These are very hard to reach.
You then remove the sprocket which has left hand threads.
To remove the shaft seal, you remove the lever, a snap ring and a washer form the shaft. Drill two small holes in the seal body and screw in a sheet metal screw to force out the seal.
Main gear seal is a little easier. Pull out the sprocket spacer and catch the edge of the seal with a seal puller or screwdriver and pop it out. You may want to replace the sprocket spacer if it is grooved where the old seal ran on it.
If you work fast you won't loose much trans oil when you change the main seal. You can start it in place by pressing it in with your fingers.
It will be very dirty under there so plan on using a few cans of spray cleaner to clean it up.
Clean the back side of the primary. Be sure to tape over the bearing to keep out trash. Use a seal puller or screw driver to pop out the main shaft seal. Drive out the starter shaft seal with a socket or screw drive.
Harley has redesigned the main shaft and starter shaft seals to improve sealing. The main shaft seal now goes in backwards. It is marked oil side.

Primary seals: 14, 13, 12
Primaey gaskets: 21, 23, 26 x 2
Screws 5 will have to be removed along with all the primary screws to remove the outer primary.
Transmission seals: 27, 24, and OEM # 12045 shift shaft seal not shown on the diagram.
Number 32 is the sprocket spacer that the main seal rides on.
Polish out the wear grooves or replace the spacer to insure a good seal.
I used HD replacement products for most of the seals and gaskets, and a James main seal kit which includes the quad seal, but Cometic will also be a good choice especially for the shift shaft seal.
