Yeah, these tranny's are strange on the SRT6, I don't know if the stock one's will do this or not since I really didn't drive mine very hard until I installed the Renntech kit. But if I'm in drive and nail it to pass a car and decide to back off it will stay in the lower gear that it changed to until you start playing with the gas pedal.
