Transmission fluid in oil pan

[cfinn]

I have a Kubota L3650 with "ever clutch." I am getting transmissio fluid in the oil pan. It actually fills the pan up to the dipstick and there is blow by.
I am guessing I have a rear main engine seal problem, but have never dealt with this issue before.
What is the problem and what am I in for?
Thanks,

Could it possibly be letting the hyd fluid in the crank case at the point where the hyd pump is being driven by the engine? Could be a bad seal at that location letting the fluid bypass.

I am guessing you ran it with the oil at the dipstick. If so you have likely caused some major problems, blown seals etc.etc.
If the hyd. oil got in when it was running then it came through the hydraulic pump to engine seal. If it filled up sitting it might have come through the rear crank.

I had this problem last year, as did some others. There have been a few posts about it. so I will keep this short.

I didn't see any damage running a few hours with hydraulic fluid overflowing out of the oil overflow.

Problem was in the hydraulic pump where it is driven off of the injector pump, bad seal let fluid flow into the crankcase.
