i have a 08 silv NNBS-
my 4l60E took a crap on the dyno, and broke the core in half. I've been having trouble finding a tranny or core , i will be using all my internals.

i got a hold of a 04 core- but they are diferrent on the oil passages. i wanted to know which yr did they start making these trannys.

 

does the 08 have an input speed sensor?

 

yes.....

 

any-b have more imput...

 

07+ got the newer style, the new body style trucks.

 

Any tranny supply store can get you a case from one of there core supplyers
