That was same as why the 260 had park brake issue bevel washers incorrect order. Waiting to see what dealer comes up with, looking for pointers to were failure could be. I'm more than happy to fix if not big cost or time with such a small coolant leak internal its hard to find and if left will course big issues.Get with your dealer. This past spring my 340 burned up all reverse clutch packs while planting. Tractor was one month out of warranty, but did not quite have 2,000 hours on it. Case covered the transmission overhaul. They said three beveled washers were installed backwards at factory.
I went ahead and traded tractor on a 340 CVT with 5 year powertrain warranty.
