For the full unlimited Duramax suite LB7, LLY, LBZ, LMM (LBZ & LMM are combined) plus both Allison TCM types (the new 6spd one is not done yet, expect in a month or two), it would be just over $7,000. That covers
both trucks and vans and 8.1L gas TCM from 2001 - 2007+.
The price also includes unlimited use of the DSP2, DSP5 custom O.S's for the LB7 & LLY and any future custom O.S's we might develop.
When pricing, just remember you get discounts based on the number of streams you purchase.
Remember the Duramax is also used in many commercial chassis (such as some of these -
