2002 Sebring transmission craziness...

I'm sure this has been posted a million times by people but here goes... We have a 2002 Sebring LXi Sedan, 2.7l with the 4 speed auto with autostick. We've been to the dealer 3 times now, and everytime they tell us the computer has the latest firmware, the fuild levels/pressures are good, all the voltages are good.... but I still do not believe them. This is what the car does:

1. Doesn't downshift when its supposed to. You will be getting on the freeway at about 40 mph, you floor the car to get moving because the rest of traffic is going 65-70. The RPMs go up slowly, the car does not downshift. Very dangerous! It doesn't do this all the time, but enough to be noticable.

1. At a red light... the light turns green, you step on the gas, the RPMs go up, you don't move. Then, CLUNK, off you go.... does this about 60% of the time. Seems to do it mostly when the car is cold.

2. In traffic... rolling at about 15-20 mph... tap the brakes, step on the gas... RPMs go up, CLUNK, then you accelerate a little bit. Always does this, no difference if cold or warm.

1. Most annoying: when coming to a stop from any speed, as soon as the hits 10 mph (while slowing down) and the car shifts from 2nd to

1st, the car lurches forward like you stomped on the brakes. You can grab the autostick while stopped and cycle through the grears, all shifts are barely noticable except for when you shift from 2nd into 1st... the car clunks and lurches a little bit. I was told by the service guys that all of the cars with this transmission model do this. I find this hard to believe. I am guessing that the trans is just not shifting at the right spot. Does this 99% of the time, warm, cold, whatever. Its sad because we seem to notice when the car DOESN'T do it...

Anyone else have these problems with this car or transmission? Is there an easy fix, or at least something I can tell my dealer to check that their supposed "specialist" has missed?

I'm just about ready to push it over a cliff and be done with it... I didn't realize these cars depreciate in value so much too!! This is the first and last Dodge/Chrysler/Jeep/Mercedes product I will ever own.

thanks!
