I agree with Mark T-but you may have a more indepth tranny issue also.Have your trans service or checked by a competent shop(good luck there).
Make sure your catalytic converter isn't plugged.
Check for a faulty coil pack or bad wires.
Check for vacuum leaks.
TRY UNPLUGGING THE LOCK UP SELINOD ON FRONT OF TRANNY
Could be a plug or wire or ecm or injector, etc
