"Clunk" can be caused by worn mounts.
"Engine race before engaging gears" is totally different, and it's the transmission dying. I'll bet it's worse once the engine has been running for 20 minutes and the transmission is warmed up.
I'd return this if you can.
Flush the fluid if you can't. And start saving up for the valve body or new transmission.
