Absolutely!! Iāll let you know when itās done. The PCM/TCM should arrive at the tuners this week, heās on the edge of Canada and the US so Canada shipping slows things up. Iām guessing a few weeks before itās driving06h3
I have a request:
When you get the rig back together; may I stop by and get a ride in it?š
I would like to know what 110:1 drive ratio feels like from an auto (vs a manual).
I've never experienced drive ratios more than 40:1 from an auto.
Awesome; thanks!Absolutely!! Iāll let you know when itās done. The PCM/TCM should arrive at the tuners this week, heās on the edge of Canada and the US so Canada shipping slows things up. Iām guessing a few weeks before itās driving
I text my old Duramax tuner to ask and he said it should be pretty easy to do it a "hacky" way - since you're DBW, setup a valet mode switch that limits RPM to 2k or whatever you want for running the welder. Then in park just throw a brick on the throttle and it'll only go to whatever RPM you set. Basically what you're doing already, but instead of finding just the perfect stick or rock to get the throttle where you want it, you just need to mash it and it'll hold the RPM you want.Yeah, I asked him. I still have AC though so I donāt think it will work
In my personal case itās a guy that was on the Colorado forums doing harnesses. I have heard good things, reached out and had him do my 5.3 harness and programming. I had a positive experience and have probably sent 10 others to him in the hummer world.How did you decide who to send the ECU too? I just picked up a 6L80 and and have a 4.8l to go in my Landcruiser but not sure who to have do the programming to make it possible.

He said he can do a 6l80e setup as well. I like using him and think heās good for the Colorado/hummer platform.
Depending on what your doing may help lead you into the right direction. Stand-alone, integrated, etc.
Yeah, cool dude. Very very knowledgeable and in my opinion, he has the most proportional looking rig on 54s06h3
Is that Bowman Transmission and Offroad in Mountain Home?š¤
Thank you!Congratulations!
I get having more overall spread with the same splits but a lot of the newer stuff is just silly emissions and fuel economy optimization. A car with fancy modern engine with VVT, variable intake, direct injection and a resulting dyno curve that has a hosepower plateau through most of it won't be made any faster by adding a bunch of gears with 500rpm drops.Just read through, sweet rig man. For future reference would you mind listing who made that shifter shaft? If you did sorry I missed it lol.
funny seeing 4 speeds were enough for 20 years then suddenly 6....8.....10, here soon the new trucks will sound like semi truck with all the shifts, fast and furious was just running future tech with a 18spd swapped charger
Thank you! The shifter shaft is sold by Zero gravity performance in AZ.Just read through, sweet rig man. For future reference would you mind listing who made that shifter shaft? If you did sorry I missed it lol.

I agree. I think there is a point of no return. I think the more HP you have along with the broader your torque curve is the less gears you can get away with. I think a 6 speed is a happy medium between new and old. An 8 speed probably works in rock crawling if the shift strategy is on point. If not Iām sure itās a bit much.I get having more overall spread with the same splits but a lot of the newer stuff is just silly emissions and fuel economy optimization.

Thanks, that doesnāt surprise me one bit, I hate my 4 speed on my tow rig and my 4 speed was ok at best during certain time periods of my H3 build. Revving or bogging is the life of a 4 speed.Congrats and good to hear your wifeās okay.
The difference in fuel economy between my 15 and 21 6.7s with the 6 and 10 speeds is 3-4mpg so not complaining there. Towing wise hard to compare with the 21 having been turned up hot from the factory, obviously big improvement. I hated towing with my old 6.0/4L80 rig, it needed a 6 speed for sure.
It seems pretty clearly the 6L80 will be better everywhere else, so Iām interested to hear how itāll be crawling.
Send me that info, please. I have an LH6/4L60E harness I want done.In my personal case itās a guy that was on the Colorado forums doing harnesses.

I had more clearance on a factory 6l80e over the special āhigh clearanceā h3 special 4l60eSend me that info, please. I have an LH6/4L60E harness I want done.
and I still go back and forth on the 4L60E vs a 6L80E.... I own the 4L and bought all the Alpha stuff for it.
Can you driveshaft clearance a 6L80E with stock stuff like a 4L60e
Thanks, I have a D300 and no doubler though.I had more clearance on a factory 6l80e over the special āhigh clearanceā h3 special 4l60e
