Here we have a good used body control module removed from a 2006 Duramax 6.6 truck with the 6sp Allison 1000 transmission. as far as I know this will only fit the 06-10 LLY/LBZ/LMM trucks with the 6sp allison if you are wanting to run your tap shift feature. Removed from a running and driving truck but may need dealer programming to work in your truck. Make sure this will work for your application BEFORE purchasing.
