Thanks CalEditor. The one you show as 2004 & 2005, does that do trans as well? I have a couple of those, one black, one not, but the same service number.
I also have a Siemens TCM that was supposedly from the same vehicle, but I was under the impression the 2004-2005 engine computer does trans as well. Why else would it need 2 x CPU's!

Cheers,

The 2004 and 2005 have Trans functions. It uses the the same block, crank, and crank sensors as the 2000 to 2003.
The 2006+ uses one crank sensor monted under the intake manifold.
The 2006+ run a E67 and a TCM. The 2004 and 2005 is not an E67. I can not find any ID markings, but I think it is a E22. It looks similar to the E22 used in the 2004 XLR. The XLR uses GMLAN/CAN and a TCM. The Sevice #'s are different between the two. I have a whole lot of XLR info, but the files are too big to send you.
