Can anyone get me a pin out for the transmission solenoid (8 pin plug off the harness) for the 2004 Grand Cherokee with 4.0/4×4 transmission?

I recently installed an 02 GC/4.0/4×4 transmission into my 04 and didn't have 4th or over drive which was odd because it worked flawlessly in the 02. Did some digging and checked the transmission solenoid plug pin outs and discovered that they are different between 02 and 04.

The 02 plug matches what I found online and I'll attach the photo here. But it doesn't match my 04 (it says it should) and I can't find ANYWHERE a pin out that matches my 04 plug.

Can anyone help? I'm hoping to be able to just change the pin outs on the plug or splice the wires to make that 02 transmission work in the 04.

Any help is appreciated!

Hi snowman_77
FWIW, FYI, unless it has been modified, all 'OEM' Jeep WJ's with the 4.0L Engine and Automatic Transmissions have the 42RE Automatic.
Here are a couple of pinout diagrams that may help you from my 04' SM:

Youre correct they do, but for some reason with out the 02 PCM installed the 04, that transmission will not function correctly.

I ended up finding pin outs for the 3 ecm plugs between an 02 and 04, but i found that all the functions for the transmission all share the same cavities in the Gray plug.

However, I am not electrically inclined at all. So I didn't dive further into the circuits and such to discover what you sent me.

What exactly is that picture explaining about circuit t60? What is that plug?

Those are the pinouts. So here is the deal, you will need a pick made for depinning those plugs. You need to compare the description and the positions for each pin for the two plugs. Then if you can find out how where they need to be shifte, then pull one out and insert the other there and keep going until you are done
