I have a 1995 k1500 4x4 that has 4L60e replaced with 4L80E.I have changed the wires in the trans plug but am stuck at the ECU cause I can't find any info on the 95 ECU.Everything I read and watch is on the newer computers.Can I put the wires in any "empty" terminal on the 95 ECU or what.PLEASE HELP

 

Did that transmission come in anything from that year with that PCM?

 

I don't think Segment Swaps are an option with them older PCM's so you're going to have to find a PCM from something that had a 4L80E from the factory.

 

I'd get a stand alone trans controller and be done with it.

 

Not sure what transmission and transfer case came out of, just know it's newly rebuilt.Seems like I should be able to move some wires around,add the ISS plug and be good just like newer ones.Im looking at controllers now,thanks for that.

 

🤣🤣🤣🤣🤣

Yeah....just move some wires around..

😆😆😆

 

After doing some googling,I moved the white wire to pin F2 and the tan/black wire to pin F3 and used them for the ISS.I've read that it doesn't matter how ISS is wired up,but I'm not sold on it so I'm still googlin thatJust for ***** n giggles,I'm gonna reset ecm and see if it works before having the memcal or whatever it's called reprogrammed.I'm a problem solver not a mechanic,lol.
