Tranny whine...

[Beach66Bum]

I feel for you. That's always my concern when the vehicles have to be checked out. I have been only going to the same dealer so I developed a kind of friendship with the staff. I might be parinoid but you do hear of stories of test drives.

It bumped up in to the 60's the last couple of days, so I've been driving around without any HVAC on...and the whine was gone. I turn the defrosters on...it's back, I turn the A/C, it's back...I turn the heat on, it's back, but not as audible. That being said, I guess I was jumping to conclusions assuming the whine was tranny related...but what else is there that would cause a whine??? A/C compressor? But then why would it whine with the heat on???

Could it be from a fan motor of sorts?

I dunno...guess that's the beauty of a warranty, because I don't have to know...haha. But the whine is rather loud, like loud enough to drown out the radio.

Change the fan settings and see if it follows that, or if it follows engine rpm.

A/C is cycled with several of the HVAC settings
