Under any conditions, first gear whines (pitch increases with RPM), all other gears quiet. Is this to be expected? I have never driven another 'Bird, or any other MN12 car for that matter. This car has made this sound since the day I test drove it.

I drained and replaced the transmission fluid about 2 months ago, changed the filter, torqued throttle body bolts, made zero difference. No material found in fluid; fluid smelled okay and was still red.

Back in the day I had a '77 Concours (Nova with extra trim), and it had a similar whine. Never had a problem with the tranny in that thing.

Let it be known that I did search and read through many many threads, but no mention of this sound.

:confused: Is it normal and I should chill, or is it hosed and I should freak?

My 95 Cougar whines when I hold it in first manually but all the other gears are quiet. I really don't think it's a problem but that's my opinion.:ssalute:

Whine

Mine whines when manually held in 1st; not obnoxiously loud, but you can hear it. I always figured it was normal...

Mine whines when put in manual 1st. It became much loader when I rebuilt the trans and upgraded the one-way clutch to a mechanical diode. I also always thought it was normal.
