One last thing before putting this thread to rest for the inter-webs archive: at least for the 90's ZJ(most likely the early aughts XJ and other associated JEEP 'RE' transmissions GC through 04) ALL of the wiring harnesses are the same color coding for the 42re & 44re's. FYI
If you have something other than a JEEP version of the 42/44re, your color coding will be slightly different.
I'm sorry to dig this old thread out of slumber but I desperately need help with an 04 WJ I have that NO ONE can seem to decipher for me.
I put an 02 GC/4.0/4×4 transmission in my 04 GC/4.0/4×4 and did not have 4th or overdrive. Which was odd because it worked perfectly when that transmission was in the 02. I checked the transmission shift solenoid (8 pin plug into top of valve body) and they are different color pin outs between the 02 and 04.
The 02 matches what's found online, the pinout list is pictured here
my 04 however does not match that diagram at all.
Does anyone have one for an 04 so I can figure out how to change the pin outs to make this transmission work?
