You're not going to want to hear this.

I went through something similar with a "known good" trans when I did my 80e swap.

Got burned, bad. New converter (Circle D 2A), HD2 and it was in limp mode, which is what it sounds like you have.

I replaced all the electronics, same thing.

I even had it rebuilt by the same guy who rebuilt my 60e a few times (probably shouldn't have done that), still did the same thing.

I ended up taking it to a different guy locally, he couldn't find the reason for it not working and told me he wanted to rebuild it...but start with a different case, a true known good core. He picked it up himself.

He suspected a cross-leak in the case somewhere, which is what I had read.

He rebuilt it in a different case and it works great. 6 weeks now without a hiccup.

I asked that he do a few things internally, one of which was the dual-feed mod. He didn't have an issue with that.

Good luck. I think you know where this is going.

Haha i was looking for rebuilt trannys last night, its looking like its going to be the trans yesterday i checked everything over the wiring,connectiond and looks ok, the only thing I'm Not to sure about is the way i tuned for it im going to show how i did it and if someone can chime in and tell me if im doing something wrong,
I went to my tune file without the Custom os
I did a segment swap with a file that had the same os and then saved. I then copied over all my tables and then did the 2bar conversion and i close it and save as . Then i plugged in and write entire.

It's not you or the segment swap.

Did you use a harness on the trans connector or repin? Did you verify 12v on pin E?

Crysis450

Yeah i re pinned and i have 12v in pin E if i didnt i dont think the solenoids would have clicked, and the same code p0756 is poping up after replacing the solenoids so I'm guessing its internal trans failure like a valve body or clutches or something. Im probally going to find another 4l80e or a th350 or th400 how hard will it be to swap one of those?
