2020+ LM2 Duramax Powertrain
I've got a 2020 Silverado with a 3.0 LM2 Duramax that has a bad ECM.
I've got a new ECM on order with the dealer, but it's already been over a month and even the Chevy corporate help department says it'll be at least a few more months before I get a new ECM.
I ordered a used ECM off of Ebay...
