The usual advice is they wouldn't have sold you the ticket if they thought you couldn't make the transfer. However, if you let the cabin crew on your flight from the US know that you have a short connection in Paris, they might be able to prioritise your disembarkation.
Once one the ground, your luggage is checked through so no need to worry about that. Just follow the signs for transfers. I think you will need to use the shuttle bus to get to 2D. According to the page on the CDG website (https://www.parisaeroport.fr/en/passengers/access/paris-charles-de-gaulle/inter-terminal-shuttles), the shuttle you will need is the Blue Shuttle, though the site doesn't seem to have a timetable.
edit: Indeed, this other page on the CDG website (https://www.parisaeroport.fr/en/passengers/flights/connecting-flights) says pretty much the same thing.
Note, this is not the N1 shuttle mentioned in Is there a way to quickly transfer between terminals 2E and 2D at CDG? which seems to describe a particularly difficult transfer.

I have just returned from that trip, and i would like to share my actual experience here, for the benefit of future readers.
Our flight from the US arrived on time - (we landed 20 min. before schedule actually, but it took us about that amount of time to taxi to the gate...)
It took me 15 min. from the gate to the bus & 23 min. the entire bus ride from 2E - L gates to 2D. (the bus was waiting at the pickup stop as i arrived there, so i cannot say about waiting time for the bus). and i made the connection alright - arrived at the gate about 10 min. before boarding started
unfortunately, as jcaron warned in his comment, my luggage didn't make it. it was delivered to my final destination 3 days after my arrival, urgh...
