No that makes sense. Reading around a bit more has confirmed it pretty much. Here's what I've wired up. If I swap the switched 12v to 87, and put a ground on 87a instead it should work and allow led brake lights. I'll do this at the weekend and report back!

This is incorrect. The 6l80 uses +12v to signal the brake switch. No relay required. Unlike the previous 4Lxx transmissions. Wire this directly to the brake light circuit. Verify the signal through your scanner.

Also, this signal has little impact on the TCC. It is still required. No TCC until 3rd gear. Release the throttle and the TCC unlocks.

Yeah but if I change the 12v to the other 87 terminal (not the one in the pic) then it gets 12v at brakes 'on' - same as if it were wired directly to the switch. And ground on the other terminal sorts out the problem of no ground through led brake lamps.

It will also need a resistor on the ground (now on 87a)... as the filament in the brake light bulb acts as a pull-down resistor to ground. That's why a resistor needs to be added into the circuit if/when you run LED tail lights (because an LED has no filament and does not allow current to flow backwards through it).

See what I mean?

I think the point here is that you only need the 12v when the brakes are applied and the signal can float when the brakes are not applied. No ground required.

OK it's moving! I wired it up with the relay and ground just in case (as I already had it installed it was easier to just move the connectors around).

One odd think though - when I'm in drive, hp tuners/vcm scanner shows the prndl status as "invalid". It still goes through the gears fine though. I might need to adjust the shifter a little, as "d6" and what should be drive are very close... but there's definitely no "drive" showing up in the scanner.

I posted this video in my build thread, but thought I would add it to this thread also to keep them all together. My new axles should be here on Monday, so first drive may happen on Tuesday and I’m stoked!

Hi guys new guy here!

Been looking over the posts on here about the LS swaps and am considering this route myself, but so far only able to find a 4L70E box, found sizes on-line comparing to the 6L80E.

AWD/4WD Transmission (bellhousing to end of output shaft)
4L70: 26.875"
6L80: 27.125" [+.250"]
6L90: 28.625" [+1.750"]

As I live in the UK sourcing parts and having to pay customs and VAT when importing could get real expensive, but have found a place in the UK that can supply LS3 engine + harness and a 4L70E box with control that I take it would be the same as the Connect & Cruise Powertrain System available from Chevrolet.

Is there any reason for a 6L80E over the 4l70E that would mean not being able to go for this set up?

GMPP never supported the 6L80/90. Therefore, E-Rod and Connect &Cruise won't communicate with the 6L80.

My adapter and other parts won't work with the 4Lxx transmissions.

Chat to Rob Butler at ORA, they import LS motors & tranny's all the time for buggy builds. Might save a few quid on shipping.

Stuff like the mounts and the shifter bracket and diff lock levers are all designed around the 6l80 and fit perfectly to lign everything up and have the transfer box sitting in the standard location. If it helps, I shipped a complete l92 and 6l80 from the us to the UK using a company that does part container loads for about 5k all in. The breakers shipped to the shipping company, then I collected from the docks a couple of months later.

latest from Dakota Digital

I had to send my control box and gauge to Dakota to get the latest firmware release but TPMS is now an option. Their kit includes 4 valves stems and 2 add on small boxes but it works fine. You have to drive about a mile to get the sensors to wake up. Most of us have the VHX-1018 gauge. I also worked with them to get a matte black ring instead of the chrome.

VHX-1018: Universal 4.4" x 11.4" Rounded Rectangle, Analog VHX Instrument

Recently they came out with the HDX-1018 gauge with center LED screen and that shows a more modern picture of the vehicle with the tire pressures. If I were starting over I'd get the HDX but I don't feel strongly enough to upgrade.

Regardless Dakota has been awesome to work with and here is proof TPMS works.

My 'LS guy' tells me that the uses (not on Defenders) exhaust manifolds from a Trailblazer SS because they sit closer to the block, giving more room around the engine. The manifolds on my LC9 are rusty, so I was planning to have them sand blasted & painted with high temp paint. Or should I get a pair of SS manifolds? GM sells them for $130 a pair. Thoughts?

I thought Nick had tried every different version of GM manifold and the only thing that worked was the Hookers. If you buy the SS be sure you can return them. I learned the hard way not to second guess Nicks R&D.

So here it goes. I have my 110 back together and working like a champ! I have put about 143 miles on it since the swap. I currently have a 1.4 transfer case. When I am going 40mph it is already at 2000 rpm in 6th gear. It seems to me that I need a 1.2 or 1.003 geared transfer case. Thoughts? Is there anyone state side that I could get one from? If not what is the shipping cost from Ashcroft? Here is a picture of her back together.

I love mine with 1.2. I think it is perfect with 3.54 gears. 80mph @~2200rpm or there abouts. I'd have to check tomorrow, but somewhere around there. Whatever it is, it sure feel perfect. Any disco, RRC DiscoII or NAS 90 should be 1.2. Below is my chart I copied from somewhere-- can't recall where or I'd give it credit so sorry in advance for that.
12D = 1.667 LT 230R
13D = 1.410 LT 230R
14D = 1.003 LT 230R
15D = 1.192 LT 230R
20D = 1.667 (2.5 N/A 110),
22D = 1.410 (all 4Cyl 90/110 bar above),
25D = 1.410 (V8 110 LT 85),
26D = 1.003 (RR Classic 3 speed auto),
27D = 1.192 (early RR Classic),
28D = 1.222 (RR and Disco I),
29D = 1.192 (V8 90 LT 85),
32D = 1.222
34D = 1.410 (2.0 Disco I),
36D = 1.211
38D = 1.211
40D = 1.211 (NAS/Japan 90&Disco),
41D = 1.211 (Disco II, diff lock stud),
42D = 1.211 (Disco II, diff lock stud),
43D = 1.410 (90/110 TD5),
57D = 1.410 (90/110 TD5),
61D = 1.211,
62D = 1.211,
68D = 1.211,
69D = 1.211,
70D = 1.211 (Disco II, no diff lock),
LT 230 Transfer case comparisons*
1.003 > 1.222 = 17.92% Drop
1.003 > 1.410 = 28.86% Drop
1.003 > 1.667 = 39.83% Drop*
1.222 > 1.003 = 21.80% Raise
1.222 > 1.410 = 13.33% Drop
1.222 > 1.667 = 26.70% Drop*
1.410 > 1.003 = 40.57% Raise
1.410 > 1.222 = 15.38% Raise
1.410 > 1.667 = 15.41% Drop*
1.667 > 1.003 = 66.20% Raise
