Default 2003 shuddering tranny

My 03 bonnie shudders at 70 or at about 2000 rpm. Anybudy ever find out what causes
it?I have 30000 miles on it so its almost out of warranty.Its been to the dealer once,they gave me some lame explantion.I read once it could be the valvebody,could be the tcc selonid,or it could be in the torque converter.Its stock and runs great other than that. Looks like i'm going to have to find a good tranny shop or take it to another dealer.I would like to gets fixed so the mods can begin.

Does it seem to be worse or at least most noticable under slight load (light throttle climbing a hill or slowly accellerating) in Overdrive?

If so, this is typically an ignition miss. Plugs and wires are the cause of your symptoms 95% of the time.

HELP!!! Sounds like I have same symptom of shuddering tranny (feels and sounds like I'm going off the side of the road where they break up the pavement to waken a tiring driver) but it'* happening upon acceleration from a stop. It seems to occur intermittently after starting from a stop and just about the time I'm through an intersection. So I figure it'* either still in first gear or between 1st and second (think the shift occurs somewhere around 28 MPH). My wife thinks it mainly occurs when the engine is warm. Ideas?

Mr. fixitall, How many miles on the car? Last transmission service? Last tune up?
Year & trim level?
