Transmission noise

[2R5]

Got a chance this week to get the car outside and really warm it up ...that noise came back , it I disconnect the tranny cable at the carb and let it shorten up the buzzing stops but as soon as I pull the cable a little bit it starts right up again......any suggestions ?
I'm not sure just what that cable that goes into the tranny does but I suspect its important or it wouldn't be there.

It wasn't low on oil but that cable was out of ajustment .

A Flightomatic Transmission will 'tell You' when it's low on fluid by that buzz!

Thanks Gordr , 2 turns seemed to do the trick. Really won't be able to tell for sure until the spring weather comes along and we can get it outside.

Thats the one.

This is the late model transmission , with oil cooler lines. It doesn't have the same linkage as say a 64 automatic , but has a cable housing that goes into the tranny . It looks to me the only way to lengthen the cable would be at the bracket on the carb, is this correct?

Remember when checking the A/T fluid level, the transmission needs to be warmed up....drive it a few miles....then check the fluid level, with the car on a level surface, engine running and the transmission in DRIVE. Don't forget to apply the emergency brake or use a brick or chock Hope this helps.

Put "transmission buzz" in the advanced search box at the top of this page. You'll see you are not alone and there is the answer.

Thats the sound!
I have recently done this car and I replaced all the mounts, I will try your suggestion on the linkage. Thanks for your input, will let you know if this makes a differnce or not.

Check the fluid level when cold and then again when warm. My Hawk leaks after 2 weeks of sitting. It generally is low and that noise has something to do with fluid level and or what was just written above.

If the throttle valve linkage is adjusted wrong, or has shifted due to soggy motor mounts, you can get a buzzing noise kind of like a bee in a tin can. Some folks might call that a whine. Transmission "thinks" your foot is into the throttle, when it isn't; generates too much pump pressure, and excess bleeds out relief valve, causing buzz.

Lengthening the the throttle valve linkage rod by a couple of turns on the clevis should make it go away, if this is the cause. If it does, have a good close look at the rubber mounts under the bellhousing, they may well be shot. Keep a record of how many turns you lengthen the rod, and take those turns back out of it upon replacing the mounts.

I have a automatic that when it sits for a long period of time it will amke a whinning noise when idioling but if you put it in nutreul it lets up . The transmission woks just fine but this noise worrys me. Anyone know what it is and if I can do something about it ?
Will it hurt the transmission if I ignore it?
If I use the car on a daily basis it doesn't seem to be there , at least not as much
........any ideas?
