Unable to program the TCM 2012 Silverado 6.2L 6l80

[The_Jason_Rogers]

For some reason I'm unable to install the TCM tune from my trinity. It will read it fine but when i go to install the tune it only installs the ECM tune and never gives a option to install the TCM. When I modify the dablo tune it gives me options to adjust the shift pressure and shift points but when I proceed with installing the tune it doesn't  program the tranny at all and the trinity shows that i have the Diablo tune installed and the TCM is still the original backup.

Im using the latest crom file available for download ( v.1r08g ) So what can I do to get this bug fixed? Do I need to post up a copy of my TCM backup for a updated crom file maybe?

Thanks,

sounds like you are on a cal id that is not supported.

if you can please email your original backup for both PCM/ecm and TCM to [email protected]


also if you can please post your current calibration numbers.

that's not the latest update... there's a newer one within the trinity forum somewhere.... search through the trinity forums for posts from Johan

Alright heres the orginal backups and I emailed them to you as well.

Lew I did see another update crom in another thread with a guy having a similar problem but I thought I needed to post up my specific backup to be added otherwise I would of tried that update.

So you ever get this fixed because im having the same issue with my 2009 Silverado and if so do you still have the file you could email me so i could try it on my trinity.
