What you describe with the shifting is normal, and is due to the converter slipping and the shift extension. The RPM's don't drop much after an upshift. You will get used to it. Do you have a shift kit?
The "jerk" you describe may be "lockup". This is programmed to engage at 38mph at very light throttle, and 40-45 if your foot is on it a little bit more. Do your RPM's drop when this happens? Watch it next time.

nope no shift kit. and i believe the rps drop a little bit but mot much. it is at the 38mph and 40-45mph marks also. just as long as its normal. i just wanted to make sure so i wasn't breaking anything. thanks for the help BlackHawy T/A
