What is the oil pan doing? LEaking I assume? If so, Where?

The po420 is a cataylitic converter code that almost always ends up being the converter in my experience. It may also set when there is an air leak in front of the converter.

P1870 is " trans component slipping" usually not a good sign. On the brighter side it is easier to get the oil pan out if the trans is out, remove flexplate and it will come out
