Theres pros and cons. The 68rfe has come a long ways since when it came out. Yes, its whole constant self learning can be a PITA and major weak point. Causing weird shift patterns and flukes. But with a a proper tune, along with a good trans tune, the truck can handle some extra power. Like a tune and aftermarket turbo.
I wouldn’t throw your setup at it lol. That combo would snap even a poor “built” trans lol.
But guys these days don’t now how to drive. People buy these 3/4 trucks and expect to drive them like a car or half ton truck. Zipping around everywhere . Constantly on and off the throttle, accelerating like a car. I see it all day, and hear it lol(the exhaust). Diesel trucks drivers flooring it constantly, from a stop light, or when they turn at a light, or keeping up with traffic, with no concept of the trucks power delivery. The torque management, how the power comes in, when the power comes on, when boost hits, when the torque converter locks. They have no idea. With these trucks you can’t get into the throttle whenever you want to. You gotta be aware what gear you’re in, what rpm’s you’re at, speed. All that. Be a driver. I mean you can do all that, but the trans won’t last. I don’t expect it too. Drive conservative, ease into boost. The truck would be fine for alittle.
