Thank you guys so much. I downloaded the new version and the "use alt key" was there. Unlocked it on the 3rd attempt. So happy i don't have to send it back to the original tuner just to have it unlocked. Thanks again.
Awesome to hear man, now you can save yourself a bunch of time and effort!

Thanks. But now i am getting a bootloader error when i try to read the TCM (T 42). The software unlocks it but then an error pops up saying something about a possible flash memory fault.
So it doesn't complete the read at all?
I know on some T42's (GTO's), the checksums are disabled from GM and EFILive complains about that (prompts for the user to correct them), but it does complete the read process.

Hi Ross, thanks for replying, this is driving me crazy, i just want to be able to tune the transmission.
When i select my controller " trans. 4/5spd T42 TCM" it shows that it unlocks on the 3rd attempt. Then it initializes steps 1-4 but then an error comes up saying the bootloader was rejected with possible reasons: engine speed or vehicle speed are not zero or possible flash memory fault.
I am trying it with the key turned to the "on" position and the vehicle is not moving at all.
So, how would i fix a possible flash memory fault?
Then engine is a 2006 LH6 out of a GMC Envoy Denali. ECM (T40 TCM (T42).
Thank you.

It sort of sounds like a bogus error to be honest.
There is a folder on your PC called -
\My Documents\EFILive\V7\Bug reports
Try to read the TCM again, when it errors, send to support@efilive.com the most recent .blx file that gets created (by date/time).
Hopefully from that we can see what is going wrong.
Cheers,
Ross

Thanks Ross, i will go try it right now and report back.
Well, it's all a bit weird (maybe!). Looking at your blx file, the TCM is not accepting the seed/key unlock code which indicates that it must be locked (like your ECM was).
Did you try the alt key option when trying to read the TCM?

Ross

Yes, i had the "use alt key" box checked. If i try it without the box checked then it comes back saying the TCM is locked with a custom code. It doesn't get very far at all. With the "use alt key" checked it goes to 3of3 attempts of unlocking then finally it starts initializing the TCM to step 4 then the error comes up.
The "use alt key" option allowed it to read the ECM just fine. I haven't done any changes (to the engine tune) b/c i really need to tune the transmission.
Thanks Ross.
