Peryn, stop while you can. As the page you linked to illustrates, the trany and the computer (ECU) have NOTHING to do with each other on your van and if you actually pay attention to what it says, it does NOT learn shift points. Your tansmission does have a transmission control module (TCM), whose purpose it is to activate the hydralic valves or servos that prompt a shift. To make the shift smooth, older model transmissions briefly held the car in 2 gears simultaneously during the shift. While most gave that up, Chrysler tried to re invent the idea, by adding the TCM. Unlike the those that do learn shift points and driving habits, i.e. the BMW SMG tranny, the late model torqueflite only measures the pressures for each valve in an attempt to try and estimate condition of the clutch bands, and compensate for thier wear.
Will one of the mechanics on this board please chime in???
