Problems are back now, worse than before.

They did *not* replace the TC.

Symptoms: jerk/jolt/extremely hard shifts (usually when pulling out from in front of my house) , higher gears isnt as obvious

occasional "rumbling" as if i am going over rumble strips

on downhill/declines car freaks out and doesn't know how to downshift, RPMs jump to 2-3k and hover there while the engine howls and doesn't stop until i hard brake and bring the car to a complete stop.

If they can’t fix it then they better bite the bullet and take this car back. And thats the thing, they don’t care. Only thing fully protects you is lemon laws and they vary by state.

Well, looks like we have some evidence that the new fluid is not going to permanently fix the problem. I hate that. Keep the responses coming guys. Just to check, I unplugged my range and drove the car a few miles yesterday. The shudder is still fixed for now on mine. No shudder on either 4 or 8 cyl mode. Plugged the range back in and am running in all 8 all the time again. I have to admit this whole shudder thing is like a black cloud that hangs over the car. I really have enjoyed the car but this whole issue does take some of the enjoyment away because I always wonder, "Is this thing going to stay fixed or end up being a major headache?"
