hey everyone, new here.. please forgive any ignorant questions.

i drive an automatic 2000 pontiac firebird.

my car is starting to sound like crap. first of all, its starting to squeek and cough. the squeeking part comes from around my transmission area. one of the wheels that turns the serpentine belt makes an awful sound. i sprayed a little wd-40 on it and it goes away for a few minutes but comes back. this has been going on for a couple weeks and wanna get it taken care of. what could it be? i had the transmission flushed a day ago too.

secondly, when i press on the accelerator it gives a clank clank sound and maxes almost to redline before shifting (from what i hear). what could this be?

thanks to anyone with help!
