2005 GTO
I am currently running a 4L80e on my 4L60e tune with the relay to reverse shift solenoid B.
As a result their is no need for the Input speed sensor.
I would like to be able to measure converter slip via the ISS.
If I pin the ISS to the TCM with the 4L60e tune will I be able to log it?
If not has anyone been able to connect the ISS to the HP Tuners MPVI with a custom PID?
If you're going to do that, you need to edit the gear ratios. While you're at it, you may as well modify the bit mask for solenoid assignments, pin it properly, and turn off the 3-2 downshift solenoid along with the TCC enable solenoid. Win win.
It would be great to have a legit 4L80e tune but changing the bit mask is something us end users don't have the ability to do.Quote:

Sure you can. You just have to request it to be added to your operating system. Gear ratios are something that hasn't been added yet, and I keep forgetting to do some stuff on my end to make it easier for the HPT people to find it.Quote:

What about the extra solenoid for TCC PWM/TCC Enable that the 4l60e uses?
I could wait for the gear ratios as I have that test disabled but it would defiantly be nice.
sent an e-mail off to support
E40 OS ID is 1250154
T42 OS ID is 24231674
support need the file that has those definitions added. I am searching the repository for one now.
Dsteck could you please post a read with that added already.
Thank You
I was able to find this file in the repository for a 2008 Chevrolet Express

HPT has been adding so many new tables it is hard to keep up ... which is not a bad thing !
However, there is something not quite right with the explanation / suggestion for the solenoid settings. Attached is a screen shot from a T42 4L80 ... you will notice the conflicting information.

That TCM OS will not communicate with the E40.*Quote:

The last two of the three bits are all that matter. I imagine the C solenoid only comes into play when using more than four forward gears.
Yes sir .. suppose so ... the description at face value is a little confusing though.
Six, half dozen... 1,0,2,3 and 1,4,6,3 both work for a 4L80. :)

If it is an issue do you have access to an E40/T42 file that has those tables already defined.
Oh, if you're just giving that as an example of one with it mapped, you're fine. I thought you wanted to use that TCM OS with your T42.
OK, Yes just sent that file to support with mine so they know what to add. It seems to have everything the GTO people need to get the 4L80e functioning without the relays and fake solenoids ( not that it doesn't work ) but it would be nice to free up some clutter and have a nice straight forward tune change and I think maybe some wiring changes ( still need to look into that since mine is already changed ). Ill check that once they get the parameters added.Quote:

Subscribing. Doing this swap now and if I can avoid buying the relays and harnesses that would be awesome. 2006 A4 GTO here going to a 4l80 this month
TCM OS ID: 24236195 here
'06 A4 GTO
I'd like to use a 2009 Colorado 5.3L 4L60E E67 PCM/T42 tune to run a 4L80E Can this be doe with a pin swap and Hp tuners? How do I get the beta with control for disabling 3-2 downshift, and changing TCC PMW to on/off, and changing gear ratios or turning off I.S.S?
So, back to the original question, any way to use the 4L80E ISS in a 4L60/70E cal?
