It is with the rear down lower than normal ride height. I am going to check my measurements after I get the truck back on the ground.

 

Also, I have a copy of that table with the transmission lengths. My 6l80 doesn't quite seem to match. It seems to be about 3/4 of an inch short. But I will get it figured out. The worst thing that could happen is I need a new driveshaft.

 

What did it come out of?

 

It came out of an 08 denali GM part #19328910.

 

Was it a 2wd or awd? Most of the denalis are awd... Got a pic of the back of the trans?

 

This is the best photo i have right now

 

Im guessing the 4l60 had the 8" or whatever it is tailshaft housing?

 

Here is the old trans.

 

Yeah thats the 8" tailhousing......probably need a new ds made?

 

It is in and running. I took it for a little test drive and it seems to be working ok right now. It differently will need some fine tuning but it WORKS. Yeahhhhhh.

Just installed the new cluster and the shifter goes in tomorrow.

I am off to eat dinner, so I will update with more details later tonight.
