Performed my 400 hour service in my 2018 B2650 a few days ago. Well, I added to much Hydraulic fluid. I know the culprit as I never pulled one of the transmission drain plugs(found out yesterday that there are 2 of those). I'm thinking maybe to much by over a quart. I just pulled her back into my garage and am preparing to drain some fluid. But I have to ask. What type of damage could a guy do to his transmission or hydraulic system with to much fluid? Any?
