SOUNDS great in theory, right? And it is, except the factory doesn’t always get things right. And just like the ECU controlling your engine, a knowledgeable person with the right tools can weave their magic to make your transmission work better than ever. Everything from what rpm it shifts at, to how hard it shifts, to when the torque convertor locks up, is all controlled by a file full of ones and zeros. Just like your engine, your automatic transmission is precisely controlled by a CU. We spoke to Paul Farrell from Geelong Performance Centre earlier this year for our ECU re-mapping article (April, 2017) and it turns out he’s big on another kind of remapping, and one you might not have heard of. Sarah Connor tried to warn us about this, but until the day computers finally rise up and enslave us all, we might as well make them work for us. It’s the reason 4x4s use less fuel than ever before it’s the reason they’re more powerful and it’s the reason every time I look at my phone it’s full of photos of people’s lunch. Like it or not, there’s always at least one computer helping us get to wherever we’re going.
We use all chevy trucks in our fleet in my bussiness we are considering going foreign,not very proud of our american trucks.WE LIVE in a digital age. I am so disappointed with my Yukon,I will never but another cmc product again,no one seems to care but for $43,000 you would think they would.
