Well, It's not the throw-out bearing. I just got done with a couple wonderful days under my car getting showered with road grime and tranny fluid... yeah, it was great. I fixed the bearing, (and the axle seals and the rear main)... but the noise came back, the very next start :|. I can hear a noise from the front of the transmission which seems to be most pronounced as the engine slows down, while sitting in neutral. I don't think it's affecting the running of the car. Well, I guess I'll just keep an ear open, and keep everybody up to date. On to the next project.
