It will bolt up. Few problems you many run into.
1. Speedometer will not work. A few people on here said you can get a VSS sensors that will work on adapting the gear in the trans to an electric signal, which should help with this.
2. I am assuming you are planning on running a Chevy 205 t case? If so, your diff on the Tahoe is on the wrong side.
If running a Ford 205, you will most likely have to remove the electric motor on the front did and replace it with a posilock 4x4 manual lever to get the front axle to engage.
3. More then likely you will have a few lights come on the dash, no big deal. if you have a tailgate on it, you will not be able to pop the hatch(needs to be in park to do so and computer will not know you have it in park due to no more single from trans).
Might be more Im missing, that just a few I can think of right now.
