I'm going to try just running both inline, with the fluid going to the tube/fin first and then the stack plate, and then going back to the transmission.

not gonna powder coat the dipstick, it's nice and clean as it

The part number on my order was 3-3-5551X NCB. It's not a strange or anything, just a NOS replacement.

I'm using the stock shifter. As part of the sale of my t56, I got the guys pedals, shifter and cable, and center console.

Haven't forgot about this thread!! Spent some time with a motorcylce I've been working on this weekend. '87 Honda Shadow VT1100. Sat for 6 years, so been doing the normal maintenance stuff, and took the carb off and began a rebuild. That'll make my first engine build over the summer, first tranny work with this build, and first carb rebuild with the motorcycle too. That's a lot of first for one year, lol.

Anyways, sprag was not in stock and should be shipped out today from Tampa (hour and a half away). And supposed to get the case back from powdercoating on Wednesday. In the mean time I can get some wiring done, mostly stuff that's in the how to's here on tech on getting the shifter to work in an M6 car. Also gonna install the wideband and pillar pod/gauge as well.

....and the snowball effect is in full swing. There's a "0411" pcm for sale local to me for REALLY cheap. Now I'm pondering swapping to a '99-up computer since I'm doing all this work anyways and retuning. Only thing is I've already wasted 2 credits downloading the stock file on my '98 (shoulda just been patient and waited until I really needed to tune it). So I'd waste another 2 credits getting into the new pcm, and another 2 for a segment swap to make the gas tank work. But, I still need to use 2 credits for a full write with an auto OS as is for the '98 pcm. So, it comes down to a bunch of time and wasting 6 total credits for a newer pcm (which is auto already), or keep what I got with a '98 pcm and just use 4 credits.

Alright, I was wrong on the cost. Just sent an email to hptuners. They don't charge for a segment swap. So either way I'm looking at 4 credits. Seems like a no brainer to me right?

I looked into this a while ago. I think there is more to it than just swapping a PCM and re-pinning. I think it involved all new stuff- gauge cluster, interior harness, engine/trans harness. That's if you wanted everything to work like stock.

The main issues between the 98 vs. 99-02 cars is the coolant temp sender and the fuel sender.

I'd do more research before picking a route.

Those issues are if you are trying to use a '99-up pcm AND harness. If you just repin the '98 harness to work with the '99-up pcm, you'll only lose the fuel gauge, which can be fixed with a segment swap. Before the segment swaps, people would just swap the whole gastank/sender.

Oh ok. Cool.

Ya, just spent the last hour and a half researching the swap. Some sensors are different on the '98 cars since the cluster reads off sensor and not serial cable from pcm. So while it doesn't make a difference when repinning for a new computer, using a newer harness will complicate things. Plus, I gotta pin in some new locations for the trans harness anyways, why not add a couple hours of torture by removing, labeling, and replacing pins, lol.

What is the purpose of running the 99-02 segment then? Did I miss this?

black00ssFL

iTrader: (24)

Faster processor, custom OS ability, more tables, more resolution in VE, etc. Not really a big deal, as the '98 computer can handle what I got....but for the long run why not? It's gonna cost me the same anyways since I need another 2 credits to write an auto OS.

iTrader: (53)

Oh ok. Well take some good notes and pictures. I might end up doing the same!!!!

Got a few things done today, and got my MWC 4l80e crossmember in too.

Here's the crossmember





And I started the long process of wiring.



Wanted to make sure my measurement of wire was correct, so I started looming the harness that I made and taped it to the longest possible route the harness would have to take.









It was the perfect length using that route. I also started doing the wiring for the shifter as well. I started looking for the proper wiring at the kickpanel for the PNP signal, as well as reverse lights. I didn't see them, so I went to the trusty diagrams. I'm my '98, the PNP signal is pin 32 on the red connector. Sure enough, It wasn't there. I figured as much since I'm still using the M6 harness. So I brought out the wiring and put a pin on a wire, ran it through the firewall, and to the shifter. Now I just gotta deal with the neutral safety wiring. I also started looking at my diagram for the 4l80e harness and noticed I need a signal to the PCM from the brakes for the release of the tcc. Sure enough, there was no pin there. So I'm gonna have to go back and see what I can do about that as well. Sure glad I bought about 5 extra pins, lol. Either way, I'll just probably tap into the brake switch wiring and run that through the firewall as well.

Good progress on the wiring. You should make a little schematic showing what pins were moved, what wires were added, etc.

The wiring to get the shifter to work is easily available searching and in the two main "a4-m6/m6-a4" swap threads that everyone refers to. I just forgot that I'm still using my m6 harness....so I don't have those wires. As far was the wiring to get the 4l80e running, I'm not at liberty to give that info out. It's very inexpensive to get that info from Slow67 and is more than worth it when compared to everything else in the swap.

Hi Guys I swapped an LS2 4L80 into my 89 S10 Blazer, these came in handy.

Great write up by the way

Stopped out to the shop today and again discovered that I don't have the connector for the tcc release/brake switch cause of my m6 harness. Well, 3 years of law school paid off and I began researching. Finally I discovered the part number. It's ACDelco PT483 just in case anyone needs to know, lol.



I found it on rock auto for about $18......or I will just hit a junk yard tomorrow. Then all I need to do is run another wire/pin to the pcm and the other side to an ign 12v source. Found the reverse and neutral safety wires, so just gotta wire those in.

Thanks. I'm just sticking with the old NPT fittins, rubber hose, and tranny cooler setup.

Thanks for keeping the thread updated with detailed pics. I just scored a 94 4L80E with less than 80k miles on it for $200. I will be tackling this in the next couple of months.

Ok....busy busy busy wiring day. Went to the local junk yard and picked up the plug for the brake switch, even let me have it for free! (minus the $1 they charge to get in). So I got ALL of the wiring issues done and dealt with. The two main things you'll be dealing with if still using an M6 harness is the PNP wire from the pcm and the brake switch into the pcm. Here's how to do it (sorry no pics):

PNP wire: This one is fairly "simple". Unplug the connectors from the pcm and locate which pin is the pnp wire. Get a 20g primary wire, put a pin on it, run it through the firewall grommet under the PCM, and connect it to the corresponding switch on the shifter.

Brake switch: a little more tricky. Get the 4 prong plug using the p/n I listed above, or from a junk yard. Now one wire needs a 12v ignition source, and the other goes to the pcm. Again, I made one 20g wire with a pin, pinned it in the proper location on the harness, then ran the wire through the grommet and to the switch. Now for the ignition source. Conveniently, there's an ign power source in the interior fuse panel. Search in the stereo section to find out where. I used just a male flat blade with a fused wire and ran it to the other wire on the switch. Then I tested it out with the trusty circuit tester. It should have 12v normally, and no power when the brakes are pushed.

During that an getting other wiring done (also wired in my a/f gauge and LC1 kit), I got to go pick up the case from the powder coater.







Then I went back to finish the above wiring project. Then it was working on getting the Trans harness in. I pinned all the connections that needed it and installed the harness. As stated above I can't give out too much info on this. And I only got one picture before I got lazy and didn't grab the camera.



Still waiting on that sprag and then I can assemble the transmission.

I was going to grab some 100W terminals...

http://www.lsxtune.com/shop/product_...roducts_id/497

And some 20ga TXL wire...

http://www.lsxtune.com/shop/product_...oducts_id/1540

Are they the right terminals? I searched and found one source that mentioned 100W.

Thanks
