9220 transmission overfilling

[jd1985man]

I have a 9220 JD my transmission oil level rise to overfull about every 50 hours. I just recently had the clutch replaced and all new O-rings put in the hydraulic pump. Jd dealer thought this would fix the problem. Just wondering if anyone else has had this problem and if oil could be getting in from somewhere else like the steering cylinders?

You would think if it is rising in the transmission that it would have to show up as falling somewhere else.

If you have cavitation in the system air entrainment may be the culprit as the air bubbles would seem to make the level read higher. I would check this next time it is reading over filled by shutting down for 30 minutes and then recheck. That would give the air bubbles time to surface.
