Flush the transmission case?

Now I've got both side covers off I can see some black sludge at the bottom of the main case, and I notice that the same black stuff on the strainer is pretty sticky and won't wash off easy with degreaser. It's not stuck on, but it's very gummy (like it warns in the manual).

Is it possible to flush that black sludge out of the bottom of the case? If so, what would I use? And what procedure should I use to do it? Straight kerosene seems to dissolve the sludge - would that do it? How could I get all the kero out once it's in?

Thanks

I've cleaned the sumps in both of my MF-35s and several Fords. The best way that I have found to do this is a weed sprayer full of gasoline. It's a piece of cake with the lift cover off but it can be done with patience through the inspection covers. Needless to say you need to take proper fire prevention precautions.
