So the other day i was out beating on the car a little bit and on the way home noticed i had developed a crazy high pitched whineing chirping sound when i let of the gas, its coming from right under the shifter.. it only does it with the clutch out, in gear and decelerating. And never does it in fourth.. 1st through 3rd are loudest but does it in 5th also.. if im coasting in nutral and begin push the shifter up to a gear with the clutch still out i can hear it starting.. so i guess it sounds pretty much like standard tranny mesh only now with an embarrassing high pitched chirp added to it..i already pretty much know one of the bearings in there let go, just wondering if anyone could point me to the knes to check..
