Tranny whine

Check you fluid levels after warming up, while in Park. Low is not good, and too hgh is far worse.

FYI Powerglides whine while in Park as a normal phase of operation. I know you are not running a Powerglide, but for those who are...

Kim, you have a THM400 or a 4-gear in this?? I summize THM400? If so, possibly planetarys? (gotta check the spelling on that one) I know I have had THM700 with a whine in second and the planetary set was chewed out on it..........

I'll check the fluid to make sure

It is the turbo 400 and I sure hope it's not the gears. How long did the 700 last till you took it apart. I don't want to rebuild it......want to change it out later with a newer style tranny

Thanks for that! I had always wondered about that whine with my old 307 PG '68 Beaumont... whether it was supposed to do that or if it was just a sign of wear.

What specifically makes the noise?

I WUNDERED ABOUT THAT TOO AND WAS TOLD IT IS THE PUMP THAT MAKES THE NOISE.

I past up on a 64 Corvette convertible years ago, as I didn't like the powerglide whine... duh..

I had some whining in my new Camaro with 6 speed auto... It stopped, after the wife got out... duh.
