CAR DOES NOT PICKUP SPEED OCCASIONALLY

2004 Nissan Sunny

Transmission problem
2004 Nissan Sunny 6 cyl Two Wheel Drive Automatic 130000 miles

Occasionally, my car does not pick up speed after a stop at the junction. Stepping on the accelerator simply revs the engine to more than 3000rpm but the car still moves at 10-20km/hr. I've changed the transmission fluid and spark plugs but problem still persists. I've to pull over and restart the engine, and it'll be back to normal.
