Well, I tried to reproduce the effect several times today to no avail. I got up to 40 mph in Drive, about 2000 rpm in fifth gear, and let the converter lock up. The rpm went to about 1500, then I very gently added gas. All it did was stay locked and barely pick up speed until I hit the kickdown point with the throttle. On level ground it just un-locked the converter unless I really mashed the pedal. On the hill it usually wouldn't un-lock the converter unless my speed dropped below about 36-38 mph, it would just downshift. I tried on both a gentle uphill and on level terrain.

Me thinks you need to take a Service Advisor on a long test drive and demonstrate the problem. If you can reproduce it that easy it should be no problem to get them to try and fix it (providing they can figure out what's causing it).
