oil leaking

What is your question?

We recently bought a 2001 town and country limited van. It has 80,000 miles and seems to have been taken care of well. I smelt oil and had the mechanic check it out and he replace a transmission selonid seal and also a oil gasket up by the intake manifold. A week later I am still smelling oil and see transmission oil on the ground. Not, sure about engine oil. Have any ideas \. Also the drivers side automatic door will close automatically but won't pull itself in tight to the van and the van lights come on that door is open. Is that an easy adjustment
