I've got a 2018 1025r with just over 100 hours. A few weeks back I noticed a small oil spot under my tractor. It appeared to be leaking at the bottom to the rear transmission at the seal (only spot that looked wet). Of course I wiped it dry, check the fluid which was good, and did my chores. Next day, noticed the spot back on the concreate. I had my dealer take a look and sure enough they think it's a bad seal. Here's the kicker. They wanted $1,400 labor plus parts and supplies to remove the transmission and fix. My until is not under warranty so hence my question. Has anyone used a transmission stop leak product successfully in a 1025r?
