The plug on the trans side was broke, only reason i 're pinned it was because the new used harness I got was different. Using a scan tool the trans is getting 14 volts and is properly grounded.

But the Trans worked perfect until you pulled the motor. And then didn't work right as soon as the new motor was put in. Is that correct?
I was thinking that it worked for a while. He survived Moab, no? But that's going back so far that I'm not sure. To much PADDING in the thread.
Sucks to hear the news that the trans may be toast. Nothing like being punch in the bean bag, while you are already down. But good on you for staying positive. Not sure I would be able to keep my chin up.
Are you getting a check engine light? Almost sounds like it may be in limp home mode. Do you have a way to check line pressures on the trans?
Yes you are correct.
Yes it does, but I don't think it's trans related and I forgot the code.
But at the end of the day the amount of material in the pan was scary
If your line pressure is low, it will cause many of the symptoms you're seeing. Could be low because of a clog or leak on either the intake or pressure side, or pump going bad.

I'm still trying to decipher this one particular question. Answer me yes or no so we can best help you.
Did the Trans work perfectly up until the engine swap and then not work perfectly immediately after the engine swap?
The reason I ask is obvious. If the answer from you is yes, then you did something and we'll have to re trace your steps.

Interesting. If it was me, I would be fairly confident that I left a wire unplugged, damaged a wire, left a ground undone, etc before I assumed the Trans was hosed.

Also, the Trans doesn't just need power and ground going to to it. It needs the rest of the info that the computer sends to it. And the computer needs all the info from the rest of the sensors to be able to provide that info to the Trans.
Not saying the Trans isn't toasted right now but, something changed that caused these issues. That something changed with the engine replacement.
Make a list of everything that touches both the engine and transmission, wires, computer, lines, etc. Which of the things on that list did you change and or adjust? You will be able to start getting an idea about what is the ultimate culprit here. Also look for pinched wires somewhere.
I say you can have the trans rebuilt and the same issues are going to be there in short order.

Yes you are correct, I'm using a tech 2, I can see the voltages, vss output , what gear it's in and when the ecm commands the next gear and other stuff.
I couldn't ask for a stronger tool to use
I took Friday off and going to try and tackle it, a afternoon isn't going to cut it. The filter and fluid was disgusting, never have seen a pan that dirty. When I used to do filter kits at work I never saw anything remotely close.
If indeed the trans is toast I'll weigh the option of a 4l80e. I would love a 6l80e but that's pushing it.
How did you get ahold of a Tech2?
What's that mean?M.A.W., after all...
you can buy them all over the internet, I have seen them for sale for around 300. I worked at a Chevy dealer for 7 years and I have friends with them. I just ask and it comes.
If it sounds like I'm jumping into just rebuild the trans I'm not. I think this one has some life left but it won't be no 100k mileage trans.

Good. Something happened during the engine swap and you need to figure out what.
It's a Greg reference! M.A.W= Might As Well
