I have a 2015 Silverado with the l83 linked to a 6l80 transmission. I really want to drop out the l83 and 6l80 and drop in a l86 with the 8l90. First of all is that even possible? Considering this would be the first time I will be swapping an engine. But then I remembered about all the computer bullshit so know I’m hesitant. I would have to reprogram the ECU
