I have a 1988 Kubota L2250F (2 wheel drive, 1100 hrs). Recently I noticed a little bit of transmission/hydraulic oil dripping from what, I found out today, is called the tattle tale plug. I am curious if anyone has had experience. The service guy at the Kubota dealership closest to me said it meant something was wrong inside the transmission case but gave no more advice than that. Any help would be appreciated. Thanks.
