Awesome man and thanks agn to everyone! Id be lost with out the help of this site among others!!
Just to double check since my truck has the 4l80e in it the 2WD version of tye 4l80e should bolt right in with minor mods like a crossmember and drive shaft

 

Make sure you get another late model 80E - cooler lines front and rear vs both at the front.

I believe someone posted previously to disconnect the transfer case control module to prevent error messages.

I will be finishing up this swap this weekend. The trans is already bolted in.

I only see 2 4WD DTCs in the tune that may have to be disabled;

Under Engine DTC Processing Enablers
P2771 Four wheel drive low switch circuit

Under Transmission DTC Fault Processing Enablers
P1875 Four wheel drive low switch circuit

 

Being AWD without a low range, I don't think any tuning should be required on the PCM. It only looks for a signal when in low range to change the shift points and WOT shift TPS%. Now other computers (BCM, etc) may look for something.

 

01-up trans would bolt in but will cost more, 94-00 trans could be used with minor modifications like one less bellhousing bolt and moving one cooler line. Two tailshafts from what I am told, bolt on (for use with 2-pc driveshafts) has splines 2-3/8" up the shaft and then an o-ring, slip shaft style should be splined all the way up. If you get the truck (bolt-on) style shaft, Jake's can hook you up with a yoke that is counterbored to work properly, mine should be here any minute. Was told that most vans had a 1-pc shaft (shorter wheelbase) and would be a better chance of having normal splines.

 

I have been looking all over for this thread.
I wanting to convert the Denali from awd to only 2wd.
Im wanting to sell all the awd stuff , tcase, diff, ect to fund the conversion.
Let me know where u r with this project. Bump

 

so doing some research on this I have awd 4l80e's that I got for cheap 1 is a 04 and the other is an 05. I should be looking at needing just the rear shaft, rear shaft housing and the rear planetary with reluctor. both trans will be coming apart for a rebuild and billet shafts and will be getting a custom drive shaft. truck its going into is 2wd. Anything im missing?
