2 Goats swapping transmissions, expert help needed

First let me say I'm looking for answers or a direction where to ask to get the answers. I'm not looking for your opinion on the idea or suggestion about buying one with the right drivetrain. And sorry if you've seen this thread on all the gto websites. We're hoping to find the person that knows the answers.


The person that is getting my M6 is doing all the work for free. It's a straight one for the other. He has a shop at his house with every tool and even a lift. He's no noob at working on cars just not familiar with the whole computer system on the car . His is an '05 with a built Level VI 4L65E and he's getting my M6 with a monster 3 from my '06. Here's the questions we need answers to.

1. Does he have to swap PCMs? Or can they be tuned respectively for their new applications?



His car (the A4) already has an aftermarket TCM from Lingenfelter.

2. Do the TCMs also have the VINs "programmed" into them?

3. If so, is he going to have to have that re-programmed as well when he installs it into my car?



He also understands he's going to have to deal with re-programming the DICs....which are also VIN-matched, as he understands it.

4. Would it just be simpler to swap every computer component from each car...PCM, BCM, TCM, DIC, etc???



I appreciate any help I can get related to getting this accomplished.

I don't think anyone here has done what you are attempting to do to know the answers to your questions. Looking forward to knowing what you run into on the swapping though. Please keep us up to date and post some pics too.

Mechanic58 is going to have a thread but at the "other" forum. Do you think a transmission place that specializes (meaning does alot of work on the GTO) in the GTO will have the answers for free or even a fee if it comes to that?

I wouldn't see why not. If he doesn't I can post it here too. Some other people are wanting to know also about what all is needed and involved to make this a 100% complete install (for both swaps) with every feature working like it came that way from down under.

Before


After



Swapped PCM, TCM, DIC, PIM and BCM. Hopefully Mechanic lists everything but I thought I'd give an update. I go and pick it on Monday and Tuesday get it completely retuned for the auto. The tune on it now is for TT's and 60# injectors. I have just cam, headers, vararam, 255 pump, 72# injectors. I will be monitoring my wideband and was told by SNL that I should be ok if it stays between 12-16 cruising at highways speeds. And yes I'm not that dumb to try a WOT even just once. My dyno for the manual was 419/393 at the same shop in Feb. Hopefully the auto with a 3200 stall doesn't eat up that much.

Is asking for 400rwhp out of the question?

Mechanic got this done pretty quick considering he was working 7 12's. And only my car is complete M6 to A4. And it doesn't hurt when you have a garage the size of football field with a lift.
