What do you mean "Was full of oil and transmition fluid"? Crankcase? Trans pan? I don't know that there is a lot anyone here can do to help, your motor sounds like it had a major malfunction, it would have to be looked at by a mechanic. Does it still spin freely or is it seized? At the very least you'll have to go through top and bottom ends to see what is intact - timing chain, crank/rods/pistons, valvetrain. If timing went out the crank sensor would shut a motor off immediately. If engine is blown dump it, either get a replacement engine on the cheap or dump the vehicle, part it out.
