Yes, I guess you could call it an RPM flare. The engine revs big time when it shifts. If I let off the gas when it starts to shift, it isn't too bad. I've been afraid to stay in it when it shifts. It just started a couple of weeks ago. I bought it and drove it down the freeway 150 miles to get home. It shifted fine. I got in stop and go traffic for about 2 hours. It was then that I discovered a massive air leak around the intake. I had to keep working the gas and brake and shift between first, second and neutral to keep it running in stop and go traffic. Once I got it home, I swapped intakes and it started shifting like this shortly after that. I thought I had adjusted the kick down properly. It is possible that I didn't get it exactly right, but I have always set up my kick down linkage the same way and never had a problem on any of my other rigs. I will adjust the bands and recheck the kick down linkage to be sure.
