Possible transmission (automatic) issue? Not sure.

Everytime I get in my car and put the car into drive or reverse, there is always a clunk immediately after I shift into one of those gears. Im assuming the sound is it engaging whichever gear I put it in. Im not sure whether this is in fact a transmission issue but I just need some insight on what is going on.

I've never owned one with an auto, but iirc there should be a small clunk going into gear.

I wouldn't necessarily say it's a small clunk, it's kind of loud. Not extremely loud but loud enough to turn heads once put into gear. It's never done it before that's why I'm quite concerned. Any suggestions? Anyone?

How many miles? It might need a transmission fluid change.

I just got the transmission fluid changed about a week ago and it didn't fix the issue.

Hey Shane, I actually took my car today to the dealership I purchased it from. I dropped it off and told the male working in the service department the issue I was dealing with and he said his technician would take a look at the transmission. I hope it can be resolved.

Could be a bad motor mount or transmission mount like The Other Andy said. Have a look at yours. There should be 4 total.
