What mechanism did you change in the column?

 

Yes I changed the enable to D5. I also ending up reflashing the BCM with an 07 2500 VIN. After I did the the TUTD started working.

There is a little more than just that but I will right it up later tonight.

 

Sweet!!! Good job, congrats!!! Details please, youre my hero for proving my theory right!!

 

Here is the latest. It has been a long day. It started with me thinking I bricked my TCM after trying to load an 09 tune. It stopped communicating and shifting. It took me a long time and about 10 different tries with SPS. I finally got an 07 Denali tune to take on the TCM.

After the trans was working again I started in on the BCM. I flashed an 07 2500 tune into the BCM and was able to get the TUTD functioning. But it locked the radio and I lost my remote start. I was able to use SPS to unlock the radio, but I still haven't figured out the remote start.

After I got the TUTD functioning, the ecm was still throwing a code for a crank relearn. I reflashed the ECM and TCM tonight with the tune I had before this morning's fun. I was then able to do a crank relearn and the DTCs are gone.

So right now I have 4 different VINs in various controllers on the truck, and they all seem to be playing nice.

Where I go from hear, is I need to send my new cluster out to get the hour meter and odometer to match the old units since it is a junkyard take out. I also need to work on my TPMS. The DIC says it needs service. Lastly, I would really like to get my remote start working again.

 

The shift mechanism that the shift lever attaches to. FYI, if you change it, you will need to remove the lock cylinder to remove the interlock.

 

What was the reason for changingit?

 

With your remote start not working did the vin you used for the bcm have remote start, that may be the problem with that!!!

 

Well I have been doing some more work on the truck this morning and I still haven't been able to get the remote start to work. I tried a different flash in the bcm and still didn't have the remote start, but I loss the TUTD. So I had to go back to what I had before. Oh well. Maybe at some point I will work on the remote start again, but for now that is a small price to pay to gain the transmission function. On a side note the TMPS is working but all fours tires are reading 6 to 7 pounds hire in the DIC then on the pressure gauge.

Wolftrk99 to answer your question, I changed the actual shift mechanism because I was thinking that maybe M mode was in a slightly different location then either 3 or 2 on the 4 speed shifter. Its not so your really don't need to change it.

Once I get my cluster back and installed my swap will be done and it will look like a factory install except for the trans cross member. And since I got almost all the parts from GM they all have a little bit of a warranty. Yippee.

Now I need to do is fine tune the trans.

 

What are the vins for that youre programming the bcm with, i have a vin for an 07 denali, that may be able to get you tu/td and the remote start working again.... I pulled the build sheet/rpo list on it and its damn near identical to my yukon save year and engine trans combo....

 

I think I will just live without the remote start for now. My XM module is also locked. I called XM and they said take it to the dealer. From what I researched, the module is VIN locked so I might need a new module so
it can marry up to the new VIN.

The PRNDM cluster has been shipped out, and when it comes back and gets installed I am pretty much done.

I will go back and revisit the remote start and XM but later this summer.
