Automatic Transmission O/D flashing and delaying engagement into Drive

I have a mazda protege with the F4EAT transmission and I just did a drain and refill. Afterwards, I have o/d flashing at startup and delayed engagement shifting into Drive. Have to wait a couple of minutes. It feels better after I apply throttle and the o/d flashing goes away after I apply throttle. It seems to do the o/d flashing and weak transmission drive response on cold starts and seem to all go away when I wait few mintues and apply throttle. Drives better afterwards. I may have seem to put in the world standard fluid when it recommended dexron III, could that be why? Or could it be the new fluid detergency is too strong and cleaned out too much gunk?
