Hi Gang, Got A " what is this " question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Big Blue · 09-01-2018, 09:16 PM

Ok, My Brother had this, he says for about 30 years. The questions are:

1. What is it ?
2. What year did it go to ?
3. And does it have any value ?

Vacuum modulator for an automatic transmission.

No idea what year though. Looks a lot like one that I had on a Powerglide but then it also looks like one I had on a TH400. Probably common to a bunch of auto transmissions.

Probably not worth much for unknown condition

Toss it in the trash. Its a used vacum modulator. Why did he keep it?

Yup. But some people keep stuff they find in case it is worth something to somebody. Or it may just have been in a box of hardware. I keep some miscellaneous chunks of metal and all kinds of nuts and bolts for when the urge strikes me to make something goofy, like this pig made from a propane tank with an expired proof test date and some feet from an old swing set. I could have used that vacuum modulator (properly modified) for the pig's snout. the spray paint cap I originally used fell off.

That is Priscilla, the Pink Pig, so my wife named her.

Thanks everyone for your comments and links. I thought that it was a Vacuum modulator for an automatic transmission also. I even showed him a VM on one of my 350 trans. But he wanted to know. He is a collector of parts he finds when he was working on cars back in the day. So thanks everyone, John

It would be foolish to toss out anyway. We don't know that it is junk and throwing out old parts is silly when there is always someone who could use it. If it has no value and you have no use then give away, not throw away. Could be the specific correct part for a restoration where the exact correct modulator has not been available for 20 or more years.

Thanks Special K, Then that is what I will do. First person responds that they want it, gets it, I'll pay shipping. Ready set,go......
