    I drive a 2004 Columbia with a 60 series and Lightning Top 2.
    A few weeks ago it broke down (first day driving it). The transmission ECU was the problem. Got it fixed in Springfield, IL and bob tailed back to Saint Louis. As I was driving I noticed the service light on the shift knob was very faintly lit when the splitter was up. It isn't lit up any near as bright as when the light comes on during the bulb check at start up. I was instructed to take it to the dealer in Saint Louis as our technicians do not know anything about this transmission. They said need to replace 3 harnesses and the shift knob. So that tell us they don't know what is wrong. Now my thought is, is it supposed to be faintly lit with the splitter up? Anybody with experience with this transmission, your input would be appreciated.
