07.5-08 tcm in a 2009-10 LMM

Have a customer now running a 07.5 tcm in his 2010LMM. This is a built tranny truck that the 2010 tcm was limiting. I tried it with a LBZ tcm and it doesn't work, but if needed find a early LMM tcm to mod the tuning on to get the most out of the late LMM.

No other issues experienced when running an 07-08 TCM in an 09-10 LMM? Stabilitrak still works fine?

IIRC, the LBZ and pre-09 LMM use the same TCM.
