ok i was driving and i noticed a sound comming from my tranny....someone told me that it was a throw-out bearing... heres the situation...im at a stop light and then i go and when i get to about 3500rpm i hear a noise thats not supposed to be comming from the tranny i cant really explain it but its bad im sure...but if its the throwout bearing how much will it cost to get replaced...? and should i jsut replace my clutch/flywheel too?? thankx for the help....approx how much will it cost to get fixed???
