I have noticed a small oil leak coming from behind the primary. It looks like it might be coming from the shifter shaft or the inner primary gasket. I noticed this shortly after I switched to Amsoil. Has anyone had this problem with amsoil, or is the leak just coinsidence. I have 42k on my road king and this is my first leak. If you have had a leak from this area I would like to hear from you. Thanx

I have a trans/engine gasket(yes they told me there is an enclosed gasket)leak. the dealer put some dye in oil to confirm this. Thank god for the warrenty. They are going to do the work this friday (day and 1/2 job!) literally have to remove tranny..ouch.

Dont know were to get this dye,but would be easier than the REDline trick and you would know for shure where the leak is.
