    Whining sound from transmission?

    For the last couple of weeks I have noticed a whining sound that seems to be coming from the transmission area. It matches engine speed and only occurs when in gear (not in park or neutral).

    Any guesses on what I might be up against? I suspect torque converter as this has always seemed a bit problematic, not always engaging right away after a cold start. Would a failing torque converter whine or should I focus my attention elsewhere?

    How many miles do you have and when was the last fluid/filter change?

    I am at about 95k miles. I am overdue for a fluid change, I think I did it at about 55k or so. Filters and all. I checked the fluid and it seems ok.

    Had it at the dealer today for them to give me some insight. If it needs major tranny work I don't feel like digging into it myself right now...

    Of course the noise wasn't as bad today as it was the last few days. After a short ride with the shop manager, he said it could be a bad alternator. I think he's on crack because the sound isn't coming from anywhere near the alternator. He suggested changing the fluid and filters and see if it gets better; which I was planning on doing anyway.
