whats is the big difference in the internal wiring on a 91 to 03 and a 04 and up 4l80e?
the harness is different. which leads me to think that when i swapped this 05 80e in something is causing the trans gauge to not read correctly. truck runs fine and has no issues. it just shows the gauges already hot before i even turn key forward. and when it gets in the middle of the gauge it says its hot when clearly its not. i can grab the cooler lines and if i put spit on the converter it just drips off.
i know its a wiring issue, but i cant find it. the extra sensor i added worked fine and the only wire you change on the main plug is for TCC and that locks up. my next thing is to replace the internal harness and hope that the built in temp sensor was just bad.
but once i saw difference in internal harness between the years i was scared maybe i have another wire to change on the main plug to make it read right.
any help is greatly needed lol.
