Well, ain't this nice. No change. I'm totally stumped here. What am I missing?

Engine is all new, block, crank, pistons, harmonic balancer, flex plate, push rods, lifters, cam, heads, valves, and sensors. All that is the same is LIM, intercooler, supercharger, throttle body, MAF.

Transmission, I just changed the torque converter, no change. Rest of trans is the same, but I still get KR when no moving, so that rules out gears, internals, and diff.

What is left? The PCM, and wiring harness.

I'm sure if I missed something, I would have found it after having the engine out 4 times and the transmission out once. I think it'* time I go over the engine bay with a very fine tooth comb. I missed something, something small and stupid.

Thanks Bill. This has become personal. If it is what I;m thinking, and I bet it'* the same thing your thinking. I'm going to face palm. And I know we had discussed it a few times. You and I both know, the list is getting VERY small.

Dang, not again.

Sure, rip one transmission apart looking for a fuse and you never live it down.

Everything has been replaced. So looking at what has not changed, that list is getting smaller and smaller. And that list is the PCM, and the radiator cap. The 97 PCM has a knock sensor in it that can be replaced. Unlike the 98+ And I can't find anyplace that sells just the module. So it'* a whole new PCM.

I've got an extra PCM sitting here, and it has a knock sensor module. PM me if you still need one.

I'm going to see what Bills PCM does. Would be nice to have a faster PCM.

Can't argue with that.
