Warm gear lever and transmission tunnel.

[BIGJake111]

The car had been sitting for a few days so I took it out for a drive today to warm it up and enjoy the warm weather, car did great. Brought it home and shut it off outside the garage. Went back and fired it up again 30 minuets later or so. And the gear lever and transmission tunnel was fairly warm. Upon start up the car had an abnormally large poof of smoke, but it quickly went away all together. The previous owner recently replaced the aos, is there anything I should check on in the car?
