As the title asks, will this TCM work with our LCT1000? Either as the 5 speed, or recommended/required/helpful for the 6-speed mod when how to perform it is released by those who know.

I dont think a white box with a red X in it will do much for our trucks. Better get the white box with the blue X

No that is for a 2000/2400 model allison. Those are used in motor homes and such. But lets see a picture of the connector.

All Allisons 2002 and later use the same TCM no matter what allison model it is. Have it reflashed to your VIN and all will be fine. I did the same thing 6 months ago.

Is there any value to having an extra TCM, ECM, or any other module for that matter?
