Subscribed.. I have a 98 Explorer AWD out back that going to be a donor for the 72 Halfcab rebuild.
So if I go this route my reworked factory harness can replace the new Bauman 4R70W harness i bought but have never unwrapped?
Correct. 4r70w control is built in to the Explorer PCM, no need for a separate controller.
Do we lose the ability to program shift points and manually lock the torque converter?
You can not program shift points yourself. If you needed something changed you would have to send the PCM back for me to change it. I don't charge for that but I ask you to cover the shipping. I do have a few tuning templates for hotter shifting as well.
Adding a converter lock up button is probably do-able. I have never tested it though. So, I'm not sure if it will throw a check engine light or not. I'm going to need a guinea pig before I can give a definite answer for that.
