Well shit. I managed to break my Performabuilt Level 3 4l60 again. WOT hitting second and something snapped, no forward but reverse is fine. I talked to the boys there and although I’m tempted to do the 4l80 swap and try to find the unicorn adapter for my nv249 transfer case, I decided to give the a Black Edition 4l60 a try, but if it breaks that will be the last straw. I have to pay the difference but it will come with a new 2 year warranty. It’s rated for 1000 HP but that’s not what’s killing these, it’s the weight and AWD COMBINED with boost. Dammit.
