I have a 1999 chevy blazer 2 wheel drive I need to find out where the transmission vacuum hose location is I can not find a diagram on line. Can any one help?

 

The transmission does not use any vacuum. You might want to look for transfer case vacuum. I know there are some diagrams on here for Blazers that are a little older, but if you search you should find what you are looking for. If I had one I'd be able to help you out a bit more.

 

2WD= no transfer case= no vacuum at all to the tranny area

 

That's the selective reading kicking in again.
