RE: Transmission Question
You have a computer that learns your shift patterns.
I have been in Transmissions for the past 25 years, and promise you are only feeling the programming. The transmission is called the W5A580 when in a Chrysler product, but it is from the 722 series and has been used by Mercedes for 38 years. You will find more information looking up the 722.6 then looking for the W5A580.
I love the way mine down shifts. We see enough brake dust, and the decel helps slow the car.
