Lambeau,

From what I remember, the 4L80 fits in our Montes without any modifications to the trans tunnel. I would imagine the 6L80 and above would definitely require custom engineering. I LS swapped my Monte about 6 years ago and felt I was somewhat late to the dance...now we're talking modern LT swaps!
