I was wrong about needing a special tool. Just before starting this job, I checked the Internet and found this...

So, this what happened. I spent an hour trying to gently remove the clip. The problem was that as the van had seen many mid-west winters the spring clip was corroded and I couldn't rotate it to find the bump so I could hook it with a pick. I was very concerned that I'd remove the clip, it would bounce somewhere and that I'd lose it, so I gave up.
I took it to a shop with a transmission flush machine, where the mechanic had an awful time trying to remove the corroded spring; he gave up and used the same disconnect tool that I bought, but didn't think was usable. It is. He said that the tool causes the spring to bulge out from its groove so that the fitting came out.
He did the job, and the transmission is much better. I think I'll try the tool on of these days just to see how it works. Thanks for all of your help.

My initial reply didn't appear to post. I tried again, and found that I could not remove the spring clip as it was corroded. I gave up and took it to a shop that did flushes.
The mechanic couldn't remove it either, so used the tool I sent in a prior post. The device squeezed the spring out from the inside so the tube slid out in a few seconds. An hour later the job was done and the van runs a lot better now.
I'll test the scissors one that I bought one of these days just to see how its done. Last note... I found that removing the plastic ring was much easier using a flat blade driver to pry it carefully off. Thanks for all your help.

Lisle makes a tool (#22930) specifically for these connectors (they are called Jiffy-TiteŽ connectors). This tool has three "teeth" that you insert between the retaining clip "lobes" and then rotate the tool, and pull to release the connector.
I had my local parts store order one, it cost around $18.00, much cheaper than the official Chrysler tool (Miller Special Tools #8875A) at $64.00.
Here's a link to a video showing how to use a similar tool: Disconnect Transmission / Engine Cooler Lines
