I tested it on the bmw x5 build i am doing now. 2019 l83 w/6L80 but have been pre occupied to work on it since December time. Hp tuners detected tap up and tap down correctly. I dont have coolant or power steering fluid in it yet, so I only ran it for a few minutes. Game plan is to finish the itty bitty little bit of exhaust welding that needs to get done so I can finanly put it on the ground and test drive it.

Next time I fire it up, I will connect hp tuners and read the shifter tap up/down and see what the transmission does and update.

not sure about the voltage thing you talked about, can you post a picture of how its wired?
the transmission will get the different voltage from the "switch" signal wire when it is in tap up and tap down mode

The flashing I mentioned of the TCM has nothing to do with the shifting or the type of vehicle it came from. The TCM communicates with the ECM over can bus. I was told by different sources that this communication cannot happen without specific information in "the OS" as you call it. The changes cannot be made with tuning. One of the reasons a stand alone controller and aftermarket control has been difficult for the newer gen 6+ speed autos. As said I chose to get all the parts from the same vehicle to avoid this complication.

I'm still having issues in figuring out the linkage to shift the 6L80e ......... anyone have any luck or options ....

I called Lokar and they insist they do not make a cable shift that allows use of the factory column ..... must use floor shifter they say

Used the Lokar rod linkage on my 6L90 with my factory tilt. Pics of linkage in the last post of my thread. I made a couple adjustments on rod since the pics to get indicator/gates in column all lining up correctly. Am a little concerned about engine/trans twist under power affecting the linkage. Will address that later if it is a problem. A little info in this 4L80 thread https://67-72chevytrucks.com/vboard/...d.php?t=756278

I have the rod style and have not had any issues. I have rubber motor mounts and a decent cam and never had any problem with it jumping out of gear.

I am not sure why their cable style ACA-1804 won't work with a 6L if you buy their ACA-1810 lever. Maybe the cable doesn't have enough swing to reach all the gears in a 6 speed? Or maybe the tap up/tap down for manual shifting?

From what I understand the 6L90 from the 2013 ZL1 Camaro in my truck is PRNDM no individual gear selection except in manual setting, which is done electronically. While there are additional detents in the shifter shaft, they are not used.

When you wire the trans for TUTD operation, you program it for D4, which is where you are stating the M/S shift is located.

I am expecting/hoping I do not have to make any changes at all in the tune for shifting except for gear ratio as the engine/trans/ecm is all stock ZL1 Camaro. Will see when I get to it.

I did install the swaptime unit. It does show in hpt a manual shift change.
(The wiring colors are wrong on the wire end of the connector, FYI)
My truck is at the tuners, hopefully be back this week. I will be able to test out the tap shift function and let you all know.

I believe he stopped making that unit. Last time I called him, he said it has a chip in the unit and the people making it for him couldn't get the chip anymore.

Is hp tuners showing the correct gear selectred compared to what is programmed for tap shift?
