My f2400 just started acting up, when mowing the steering does not seem like it is synchronized. However I also noticed hydro oil leaking out of the overflow. We changed the trans oil before mowing season and I have a feeling we might have overfilled trans slightly. We drained about a quart out of the trans and ran it for a while. The problem got better but not all the way. This was yesterday, today I mowed with it and the problem was gone. Now the question is if the problem was caused by overfilling the trans what if any damage could have been done?
