Pull engine and trans together?

If I remember rightly Fel-pro has just the part of the gasket that goes between the pan and the timing cover. I'd pull it and find out if it's stripped, like you said. If it's not, get the Permatex oil resistant gasket maker and snot it.

Then pull the trans separately. I don't think I'd go through pull the whole rig just for a timing chain cover/gasket section.
