Probably not the transmission but the Fuel management, which is inactive in L9.

With that type of level, I'm not sure if one company is better than another. I went wit RC just because I already had stock GM blocks from my last truck to use and only needed the front level.

Just put a level on it and add small blocks to the rear.

I had a similar issue yesterday where there is no sound from the radio or voice commands. I can raise and lower the volume according to the bar indicator, but it acts as though it is muted. I tried turning the truck off several times and still get the same issue. This morning everything is fine. Glitch? I'm taking it in for service soon and will ask then unless it keeps happening prior.

Thanks.

Get a B&W hitch or the lockout switch if you want to keep it on. I have always kept my htch on my trucks in the past 1. No one needs to walk that close to my truck and 2. It has saved my bumper more than a few times.

There are 2019 trucks without the cut outs, not sure what trim level. You may be able to trade someone.

Anyone have experience using their GMC Reward points and how did you go about doing it? Are they only good thru the dealership or can you purchase through GMC online?

2015 SLT 4x4 stock blocks are 1-1/4" and will work with the new 2019's. I have my old blocks as described on my 2019 Denali with no issues. You will need longer u bolts.

Look into GatorTrax exact same cover as the Retrax, but a few hundred cheaper. Mine even had Retrax labeling on the inside of the shipping box. I had the powder coated RollNLock on my last truck and had no complaints other. I do like the low profile of the Gatortrax/Retrax even though it takes up a little more room in the front.

Look at luxwood trim. I believe theirs fit around the emblems.

What size tires are you running?

I had it leftover from my 2015 gmc. You may be able to find some at a local 4x4 shop.

Looks good by the way. What size tire and wheel combo?

That is the spring perch with the silencer pad. The block will go between it and the leaf spring. If you go 2" & 1" it should give you the same look as above but 1/2 inch lower.
