Default Whats the next step here????

I bought an '89 12 valve cummins (just the engine, no truck). Seller said it was recently rebuild (evidence supports this) but had been sitting a while and would likely have it's pistons frozen/seized as a result. I got it at a good price so picked it up.
I have pulled the head and cylinders1-4 look in good shape. 5&6 a bit rusted (maybe a de-glaze/flex hone job or maybe take it to a machine shop- don't know yet).
Now that you're up to speed, here's the question.

I've had all cylinders filled with automatic transmission fluid for ~2 weeks. Cylinders 1&2 drain themselves. But 3-6.....nothing. I can't get them to move or the engine to cycle. So what's next?. Pull the pan and try to get the pistons out that way?. Hook the starter up and try bumping it? Let it sit longer soaking and pray? Strip it and scrap it?. Help pls

I'd hook up the starter and bump it several times and see if they break loose. cant hurt........
That will certainly cut the wait time for sure..
