Ta da!
Holy crap it's a beast. The tranny issues turned out to be nothing. It was throwing 4 codes, which immediately made it seem like a wiring issue. No way 4 pressure switches and sensors would all be out in a new transmission. Sure enough, the big electronic connector's swing-arm lock was in the wrong position. Started up, and no codes. Woot!
So I took out on the nearest big road to do some sprints to 60 to set in the rings. You can feel the ECU fighting the cams. If you give it moderate pedal, it kind of surges and falls off on its way up to forty. But if you hammer it, it spit fire. It doesn't even have the headers and y-tube on yet, and it sounds like a demon. Unfortunately, it's all over the road, so I need to get it in first thing for an alignment. You can see how jank it is in the picture up top. There's still tape on the grill too--need to finish painting that too.
Can't believe it's been 10 months. My snowboard racks are still on the roof from the winter storm before I swamped the motor. Can't wait to get this thing in the snow.
