tranny fluid vanished !!

[Nvblazer]

I have a frustrated 88 Chevy Blazer !

I started noticing large quantities of smoke exiting my tail pipe !!

I noted loss of tranny fluid, I went and had any and all leaks repaired !

Still loosing fluid (no leaks) and smoking up the street on take off, real good after a long idle to a stop, then bam ! smoke screen city!

I was told about a modulator valve could be my problem sucking tranny fluid into the exhaust ?? Got any knowledge of such a thing ??

Well hell I went to the parts place to get a modulator, and turns out my tranny does not have one, now I am really confused where the smoke is coming from. I did find a small drip from the front seal area but not bad enough to loose that much fluid ? Gonna take to GM and let them figure it out. Can't be much else wrong with it I rebuilt the carb and put a new motor in. And as a added bonus it starts missing bad again today....

There should be a vacuum source from the engine. That's surely where you're atf is going.
