Interested transmission flash fix people please step inside...

OK so I've compiled together a list of all the possible TCM's that I have found:
If anyone has one that is different please post it here along with the year.

I am also going to list the ones that I can currently flash, and the ones that I need donors for.

Thanks everyone!

0C8927750G Can flash now!

0C8927750AK I need a non fix donor for this one!

0C8927750CF Can flash now!

0C8927755 Can flash now!

0C8927755R I need a non fix donor for this one!

Again please let me know if any of you have a different TCM part number!

What does your "flash" actually do?

VW Touareg models are as follows:
Generation 1: T1 is model 7LA & facelift T2 is model 7L6
Generation 2: T3 is model 7P5 & facelift T4 is model 7P6
Generation 3: T5 is model CR7 [Not available in "VW Atlas" North America!]

I suspect return the TCM to pre-fix state. Hence the request for a "donor" unit i.e. a unit to suck the non fix image from . . . my guess . . will see if I am correct

I have both a fixed AK and a non-fixed Eurospec AK, but they have different software versions. I don't know what the firmware differences between part numbers are, but It seems like the 4-digit software revision makes all the difference to shifting behavior. My original TCM went from "Component: AL1000 AISIN 001 2269" to "... 3398" after the fix. So you may be able to apply a tune from another P/N as long as the software revision is similar. Might be worth exploring!

Toiler is correct, It will revert the TCM back to pre-fix status that everyone has come to love

Yes the software is like different versions of windows, newer isn't always better

What's the 4 digit software version of the eurospec AK?

It doesn't seem to read the same as the US modules for some reason, just says "0000":

Well now that's interesting!

Coding is very different as well, 0045416
Did you try coding to what your original unit was?

I am looking into cross flashing different software into different modules.
There is some different software available that I am going to try and flash to my TCM that may offer something for people with tunes. This is not a custom tune, but still factory stuff.

Not sure where it reads the 7 digits above. The long coding helper in VCDS still seems to read the same; it was 001168 originally, and now running 00B168. Shift patterns jibe with the pre-fix behavior, but some shifts are a little rougher; I can feel the torque converter engage, sometimes a little lurchy, especially between 2 and 3, where it was pretty smooth before.

Thanks for doing work on this!
