88' GMC Jimmy Repair Manual

I have a 1988 GMC jimmy that won't shift into 3td gear, now I have found a vaccum tube disconnected from my transmission, the only problem is that I have town other tubes that arnt connected to anything. I was wondering if anyone knew where I could download a free PDF of a Chilton or something like that. Or maybe a diagram that may show where all of the vaccum hoses in my engine are supposed to be connected? If you have any information pleas reply. I'm lost here.

You can go to a library and look at a manual even copy a page you need. Normally a copy of a vacuum diagram is on a big sticker in the engine compartment.

The diagram under the hood does no good. I need something way more informative than that.
