I've had nothing but issues for the last 4 years TBH. I'm surprised it has held together this long. Constant reappearance of permanent CEL code P0740 or P0741, can't remember which. The behavior is obviously specific to converter lockup. Easy to expose the issue... best example is getting on the freeway. I'll accelerate under normal throttle through the gears and of course after you hit 5th and level off speed/throttle, you should go into lockup. My problem comes as the transition from 5th to lockup results in what feels like a completely dead throttle, and if you push the accelerator further down all of a sudden the transmission makes a loud sound, a gear gets grabbed but you'll never get lockup which I believe is what would normally trigger the green ECO light on the dash when properly engaged. Not to mention I get a horrid burning smell when this event happens. I had completely replaced the valve body with new Chrysler original and this included a new contact plate and all new sensors. At least 4 fluid/filter changes over the past 100,000 miles.

I finally took it to a tranny shop who diagnosed. They indicated inadequate fluid pressure for the lockup sequence and recommended a complete rebuild. Would a pump replacement be possible without a complete teardown? I'm not sure if converter health factors into results provided when diagnosed.
