Dealership still has the truck. Now they say its not acting up. At least the svc advisor got all the active codes when I brought the truck in. Transmission codes, loss of communication, etc.

This morning I started my truck to go run some errands and the check engine light came on before I pulled out of the driveway. When I backed out and put it in D, nothing happened. Tried again and no go. Barely revved the engine and then finally went in gear. Drove down the road and never felt a shift. Was going around 30-35 mph at 2500-2800 rpm. Sped up and slowed down, never shifted. I am guessing i only have 4th gear. Took straight to the dealership. Tech looked at today but couldn't figure it out. They said they should know something next week. Truck only has 12,000 miles... Hopefully its an electrical issue, we shall find out next week. Anyone else have a similar issue?

It came really close to getting the Borla, they sound great! I don't think you could go wrong with either one.

Just got the gmpp 'Corsa' exhaust installed on my 2018 6.2. Very impressed so far, no drone on highway and no helicopter sound when going down to 4 cylinders. Just what I was looking for as far as sound, not too loud on cold start, quiet when cruising, sounds great when you get into the gas!!

When you look at exhaust systems in gm accessories, there are a couple systems that are not labeled Borla. I saw somewhere on here that Corsa made the system. I have heard the Borla systems and like them, I just want to hear what the other system sounds like before I buy.

Awesome!! Let me know when I can place an order.

Has anyone done the GM dealer installed Corsa system? I am likely going to get the gm borla system, but would like to get input from those that purchased the Corsa system.

Just bought a 2018 gmc 1500 slt and cannot wait to do this mod!!! I will try to read thru most of the thread before I start bugging everyone with questions...

Traded in my 2016 2500 for a 2018 SLT with a 6.2 and max tow package! Loving it so far!
