Shambo, your question was/is actually a good one. Are there other ways of doing it other then the way that Marco is currently doing it? The torque management/shift defuel issue goes back over 10 years on our trucks. It started on some of the 2000's and then in some form or another it still exists today. The way it is done, seems to change about every two years. The 01's and the 02's do it differently then the 03's and 04's. In some 04.5's and 05's it changed again. It also seems to be different on some of the California models.
The end result is that the way Marco does it works with all the 3rd gen models. Not having the gear indicator doesn't bother me, but Patty has mentioned it a couple of times.
I hope you didn't take my earlier answer as being "flipant". It was not meant that way at all.
