ISO help with t-case swap

[Gabe Binkley]

I have an 07 Cadillac Escalade Esv and it's got a texas speed cam, stainless long tubes, tuned on 93.. long story short my factory awd BW4485 (NR3 RPO) is about to go out and I would like to swap in either an MP1222 or a NP261HD.   The MP1222 comes in 08-13 silverado 1500s with 6l80es, it is a manual floor shift unit which would be easy to make a linkage for.  The MP1222 or RPO code NQG that I'll need if I'm correct is a 32 spline unit that would have came behind RPO code MYC or 6l80e transmission.  I'm looking for any knowledge, if it can be done and what all I'll need to change.  Thanks in advance
