Rev match? Even with a auto it's a good idea to rev match to some extent when shifting back into gear. This reduces the shock on the tranny. With a torque converter you don't need to be too fussy about exact rpms as you may want to do with a clutch, it does a good job of soaking up some shock, but it also amplifies torque.

You'll feel the jolt, try to minimise it. At near highway speeds I give a brief stab of throttle to before popping back into drive, feel less jolt that way.
