I bought this used 2006 corolla ce few months ago with ODO at 84k. Now for few days, I am noticing this sound that starts to come out from the hood when I stop at red light with car in D and foot on brake. This screeching noise appear few seconds after stopping and gradually increase in intensity. It disappears as soon I start to drive again or if I shift to neutral. Seems like problem with transmission. I just had an oil change and fluid check a month ago. Just wanted to check with you guys what should I expect to hear from the service center and potentially what kind of repair cost I am looking at (kind of low on $$ these days )
