How do I trouble shoot the TC circuit without a scan tool?

I know there is the purple wire with yellow stripe, it should lock up if I ground that.

So where does it get it's power? Is there more than one wire that controls or supplies power to the TC convertor.

I am looking for ways to test the TC circuit inside the tranny so I can figure out if my problem is internal or external.

its a pretty expensive gamble. I payed a 108.00 for mine rebuilt, or whatever you want to call it, just not new. but, I had mine scanned to confirm it was bad. my symptoms were, it shifted fine until it warmed up. bad solenoids obviously don't work as well as they should when hot. hope this helps
