1996 GMC Sierra club cab 4x4 just quit running when , I was driving it . Sounds rough when runs does not smoke. Was full of oil and transmition fluid, hard to tell where the sodd sound is coming from. Please help, do not have a lot of money!

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.
