DrX, ole buddy, im now interested in swapping in the 2001-2 411 pcm from a whatever v6 vehicle,
the 2001-2 3/4 ton express van that ran the 4.3 and 4l80e wiring diagram would be most helpful,
do you got acess to that diagram? thanks~ truckeez
the 2001-2 astro vans also ran the 411 -with that pos 4l60e.

That's exactly what I was wanting to confirm! Thank you!
and for the record even though my post count isn't high doesn't mean I haven't been around for quite a while. I typically stay quiet and read everything I can until I have confused enough to have to post lol!
Still unsure what way I want to go on the tune portion as I am new enough to tuning to be extremely dangerous. So far my abilities are raising the top speed and disabling the rear o2 codes lol.
I use efi live v2 mainly because I have a dirtymax and that seems to be the tuner of choice for he diesels. Seems the norm for most guys on here is hptuners. I'm fairly certain I could manage a segment swap fairly easily as I have a PCM from an 03 2500hd with lq4-4l80e combo. I'm guessing I could use my truck as a mule to plug the 03 PCM into, copy the calibration file and then swap back to the original PCM. Then I could copy the transmission segment over to the current file I have for my truck. I would rather have the torque converter stay locked up at 0% tps though which is what turned me on to this post.
Lots of very good info so far

Where can I get the pcm connector pins for the extra vss sensor for pin 22 and 23?
I saw these but not sure if they are correct

4l80 swap on a gen 4
ok guys, This post has solved alot of problems, maybe it can solve mine.
i swapped a 4l80(converted to 2wd) into a 09 silverado, I used the harness adaptor from pcm of NC, i got it running, but the speedometer is way off, like it says im doing half the speed i am actually going.
I changed the few parameters in hp tuners that the instrutions on the harness told me to.
Im wondering if i need to wire in the front ISS speed sensor? currently i just have my stock 4l60 speed sensor plugged into the back.
please help!

2003 4L80e only has ISS, no vss on rear
Good day all, im doing a 4.8/4L60 to 6.0/4L80 swap in my 05 half ton. I've got an 04 6.0, and an 03 trans but it only has the front input speed sensor, the rear just has a factory plug. Can I just swap the vss from my 60e over into that spot or what do I do. I've read the stickies lots maybe i missed the answer. Thanks!
trans was from an 03 1500HD if it matters
