T42 4L80E cal.

[HOWQUICK]

Hey guys,

Iam after a suckout from a T42/4L80E equipped 2007 2WD truck, ideally OS 24239036 or 24239927. 4WD cal may work. Anyone help out?

The 2007 model year T42s started out with OS24235341. Some of the 4L60/65/70 calibrations were updated to OS24239036, and then OS24239927 (which was used in the 2008 model year). I have never seen a 2007 4L80 T42 calibration with anything other than OS24235341.

A little more information about your project, and why you want this specific OS, may lead to some suggestions ...

Taz, I was trying to help out HOWQUICK as well and I had several T42 OS's of 24239036 from 2007 trucks, but all 4L60E.
What doesn't make sense about what you wrote is 24235341 is a 2006/2007 OS, 24239036 is a 2007/2008 OS. Normally GM's TIS updates would not jump from one year to the next, but, I don't have a vast collection of T42 files so I am happy to stand corrected there.
I understand the project they are working on and I won't say much because it's not my place to, but having either of those two OS's is going to make life much easier to integrate to a base T42 tune they are already using.
But if you are saying that the 4L80E never came out with anything other than 24235341 then that is what he is stuck with I guess.

Hi Ross,

I queried some 2007 truck VINs via TIS2WEB - and that was the result. Some continued to use their original T42 OS24235341 (no update), and others were updated to 24239036, and some others were updated to 24239927.

The pattern seemed to be that the 2007 4L60/65/70 were updated, while the 2007 4L80 was not.

I'm not saying there isn't an updated calibration for a 2007 4L80 - just commenting that I have never seen one.

Going to need more information to assist further.


Cheers,
Taz

That response doesn't shed much light on your project ... makes find a means to assist somewhat difficult.

we are doing a platform change with a 4L80E. The latest CAN based OS is all the assistance I require thanks.

OK ... sounds like you have a very specific calibration in mind ... I would suggest you download the specific calibration you want via TIS2WEB

already tried that and they aren't available even though the trucks are on the road...hence the post to see if anyone had a suck out.

thanks for your reply. 2007 and later T42/4L80E truck is what we are after. None in this country so up to our US cousins to get us going!

[Boost]

Here are a couple that I THINK are it. How would we know for sure? They are from a long time ago (Sorry I am tired as HECK!)

[HOWQUICK]

thanks guys. Specifically what I need is as follows;

The 4L80 continued use in GM's truck line-up like in 2007 when it was introduced into the Suburban and Yukon XL vehicles with the 6.0L engine with OS 24239036 or 24239927.

can anyone help?

if you have a vin for the matching os you require, it might be possible to use gm-tis to flash it? I have a spare t42 i can try it on.

i found 1GKFK16347J188333 which comes up as a v8 with 4 speed from a yukon xl denali from a carsales website. os's is = 24235341 from gmtis

nevermind, read the first page...

ok, found this vin 3GNFC16008G206660 which is a 2008 surburban from this car add.
http://www.carsforsale.com/used_cars_for_sale/2008_chevrolet_suburban_195951420_2#
it has the 24239927 os you require.

however im not sure if its a 4l80. apparently the express van has the 4l80e http://www.carsforsale.com/used_cars_for_sale/2009_chevrolet_express_208021576_1#
that cars vin says it has os 24243356 that suits an 09 ecu

this vin 1GCGG25C681175366 suits an 08 e38 and has tcm os 24239927 , ecu os 12617631
