Groaning problem

[socomboy]

Guys I got another quick question. I've noticed that when I switch from park to drive, I hear a groaning noise of some sorts. Now naturally when switching gears you will hear it but this groan is somewhat loud. the expy also groans for may 2 seconds during takeoff and then is disappears. Any suggestions?
