Did you reset the computer after the new part was installed? That needs to be done after parts are replaced so the computer can reset it's programming for a properly functioning part. If after the reset you still have the problem then the system is going to have to be live data scanned so the tech can see what is actually going on with the sensors and the ECM response to those readings. It is possible something else could be out of specs.
if your torque converter is going this can happen its often called sliping. Also if the trany gears are worn they can slip while they are in motion.
