whats the difference between a 2003 and 2004 4l80e
yards say the 2003 and 2004 show not to be compatible with each other. whats the difference? im looking for one for my mustang ls1 conversion. I have to buy drive shaft and converter anyway.
I had a newer harness and older NSS, so I cut off my large single-connector and spliced on two smaller connectors... which means I have the single-connector you will need for the newer transmission. If you want it, PM me and I'll send it to you this weekend.

1) I think in in 2004, they started the new "single-plug" on the 4L60E as well.
2) If you're getting a custom wiring harness made, just tell them to put the plugs in for the 4L80E. There are places (like Speartech, a sponsor here) that will sell you the wiring that changes a 4L60E harness to a 4L80E harness. I think they will reprogram your computer as well. This whole ordeal is not cheap, I think north of $200. Just have the person building your harness wire it for the 4L80E. You will also need to have the PCM reflashed to work with a 4L80E, if it isn't setup for it already.
For a car the neutral safety, reverse lights, hatch lockout switch is on the shifter in the car.
