At least they are gone. I hate having things like that sit around.
Thats almost half what I paid for them and I got half the life out if them. They sucked anyway!
Sounds like a win to me. Congratulations on the sell

Did a little Autocal programing tonight. Last fall I asked Blackbear for a TCM tune that would hold 1st gear longer. They delivered and it did hold 1st longer, not quite as long as I would have liked but it was better. I have driven with that tune for a while now and noted that the trans would hunt, downshift a little soon with slight throttle increase and it would flare the 1-2 shift cold sometimes. When I got a new set of tires that were 10lbs. Lighter I noticed it would hold it’s gears longer before a downshift but not in a lugging way.
So, I decided to try loading my first MODTCM trans tune file to see how it would perform. I still feel like it upshifts a little sooner than I would like but I think its better this way. It does hold its gears longer for nice, hunting free, city driving and she still runs like a scalded dog when I get on it.

One thing I wish I knew was how to load my Autocal with separate files. I currently have two quick start files. One from 7/22 and one from 10/22. The former has the first tune files and the latter has updated files for both the ecm and tcm. I wanted to load the newer ecm files along with the older tcm file but couldn’t figure out how to do it. I wondered if it was something to do with creating a new quick start file. I was a little gun shy to mess it up. Any pointers?

Iirc when you open a QuickStart file, it overwrites the old file but it’s been awhile since I did it. That was one of the frustrating things about Blackbear for me- the inability to ask them a technical question over the phone, like how to do what you’re talking about. And if you send in an email, you have to ask every possible question. And then if their response raises more questions, you go back in queue. It could take weeks to get an answer. They used to send files separately so you could just cut and paste them, then they went to the QuickStart format which confused me. You can always copy all tune files from the Autocal after running the QS each time, and delete them completely off it and them copy them separately onto the Autocal I believe.

I think I figured it out.
Referencing this. The method I used seemed to work but I may mess around with it some more.

Just placed the order for my replacement dash. Part number 23224742 from GMPartsNow. Used the 50% Shipping promo code. Came to $514.21 shipped. I didn't want to replace the dash but I am afraid the part will become unavailable sooner than later and I don't want a busted dash.
And, it is supposed to show up tomorrow! I will be in NC tomorrow so I will have to let my 5'3" wife handle it.

There's a video on youtube I watched when I did mine. Dude is really rough with stuff but looks like its at the dealer. He's filming with one hand and doing everything else with the other. It took me about two hours to swap them out. I had to take the airbag back out because I forgot to put on bolt in under it. During that, I put a tiny little scratch in my brand new dash with the bottom of the airbag....lol

You won't regret replacing it. The only regret I have is not getting the update part number because I wasn't aware it existed or even that they continued making the non-revised version. Casey ordered it for me through is work, off the vin. I just assumed it would be the newest part number.

Funny thing is, I only have the small crack by the air bag so it seems wrong to replace it now. I know whats coming and as Mrs GeorgeB said “get it before they stop selling replacements”. So the new one is on the way and will get installed whenever I get around to it.

I thought the tab in the middle broke also, or was that someone else that posted the pic with it zip tied?

Yes, thats me. I had some breakage occur on a washboard road. Boy! That dash flops bad on those!
My 2011 didn't have any cracks, but that tab in the middle was broken and it would bounce over bumps. I pulled the front defroster area up (need to remove A pillars first) and put a small strip of heavy duty velcro, the kind that snaps together, in that area so the two pieces hold together better.

It seems that stiffer, sturdier defroster strip is designed to hold the center of the dash edge up. When that tab breaks, the center starts sagging and bouncing

I believe the tab broke when I was running that washboard road after the dash warmed up in the sun. I could probably get away with some velcro in that spot and a small plug for the little hole I drilled but if I am going to take that panel out I will have a replacement handy.

Did yours eventually crack?

My new dash arrived along with the forward filler panel. I inspected for damage and all seems good. I am surprised how flimsy if a piece it is even though its the updated design.
whenever I get around to ordering one I plan on epoxying some Popsicle sticks or flat bars or stiff plastic or metal or whatever is handy underneath it to strengthen it up in the weak spots

like they tend to break around the cluster, around the center speaker (if equipped) and on the thin strip in front of the passenger side aribag.
