Yeah pretty sure you need to follow the instructions exactly including the parking brake and have it in park. I remember now that I did do it once when I swapped my PCM on my 02 and I tried it without setting the parking brake because I figured since it didn’t work there was no point. It didn’t perform the relearn until I did that. I have since swapped my original PCM back in and I don’t think I ever did the relearn with this one. I’ll do it today just to be sure it’s done.

Wait, I forgot you'll be doing this in the scanner. In the vehicle functions you can command gears (remember you doing this on the 4l60?). I'm not sure if it has the option for "park" or not, but thats where I'd look.

That's what I was afraid of.
Yes I believe I can command it but IDK if the ECU needs a signal return to confirm its in park or not.

Ah, possible but maybe not. Give it a shot. If you have to have the signal, you can probably find which pin triggers that on the pcm and maybe ground that wire?

I was thinking that, I need to reinspect my trans temp sensor wire anyway I think it's becoming intermittent. A lot of this stuff will have to wait till after the head swap because it's getting tore down Saturday for sure.

I'm super excited to drop the oil pan and see what's up, I'd be tickled to death if I saw ARP bolts or studs anywhere in the bottom end, or even better something forged lol.

Hey, just be happy if its super clean and you see no bearing material. The rest will be a bonus! lol
Are you doing the o-ring? That why you're taking the pan off? Good thing its 2wd, those are cake!

Yep O-ring is the main reason, not because I think it's bad but because I don't know its history, and if it's 17years old I'd rather replace it now than when a rod loses oil and a piston smacks the new heads. I'm also just really really curious how the bottom end and oil pan look.
