#1 of 3 High Idle with 2000 Venture

I have a high idle problem with my 2000 venture extend van; Here is some history:
Van has had the problem with the bucking transmission. Shut the vehicle off, and then it acts fine. I know I need to have the transmission modules replaced. However, this problem has stopped for some time.
Now the vehicle idle increases to 3k or higher. I noticed that most of the time it will idle normal when I start it, but will increase in idle when I shift into gear.
I’ve shot W2 along the hoses to find a vacuum leak, but found nothing.
Repair History: I did the lower intake manifold gasket myself last year and replace plugs & wires, water pump, injector o-rings, and a few other things. I’ve had the dealer replace the IAC two times.
Because the high idle occurs when I shift it into gear, could it be the modules on the transmission?
Any other thoughts?

Check engine light on?
I don't think its transmission sensor related in my opinion.
Sure sounds like it could be an air leak somewhere. I had a Check engine light that baffled me and my mechanic and after doing a little research I found that the wrong PCV valve had been installed and was the cause of the problem. A $ 5.00 part was the source of 2 weeks worth of headaches.

No check light - that's the confusing part, but for $5, I think I'll stop by a dealer. I did replace it when I did the IMG job.
