I found this diagram while looking on line. It says 4L60/70/80E at the top but I thought between the 60/80 a few wires had to be moved. I know this might not have correct wiring color ect but it shows the pin assignments for the controlls from the PCM to the tranny itself which is more of what I am interested in. I have a M6 F-body harness I need to plug the 80E in to.

look at 4L80E connector key page #2

 

Ok I have almost the whole thing figured out by doing searches and comparing this diagram.. BTW, this is the most complete diagram I have seen for any 60/70/80 tranny. Very helpful!!!

Here is what I have figured out for 99-02 F-body PCM location to tranny connector.

If anyone knows where the missing 2 wires connect to the tranny connector that would be a big help. I'll be looking at a stock 60E connector that was hacked when I get home to see if I can figure it out.

Function ___ Trans Connector ___ Connector ___ Pin
Shift sol a - (1-2) ___ A ___ Red ___ 48
Shift sol a - (2-3) ___ B ___ Red ___ 47
Line pressure + ___ C ___ Red ___ 6
Line pressure - ___ D ___ Red ___ 8
tcc, 1-2, 2-3, 3-2 + ___ E ___ ? ___ ?
ATF temp + ___ L ___ Red ___ 51
ATF temp - ___ M ___ Blue ___ 53
Range A ___ N ___ Red ___ 63
Range C ___ P ___ Blue ___ 18
Range B ___ R ___ Blue ___ 17
tcc pwm - ___ S ___ ? ___ ?

 

Anyone??

 

Try again with that link. It's abbreviated.

I can't get it from abreviating..

 

Just need to know what pins on the computer are for the TCC + and TCC -...
