Hey guys. Have a customers 2009 C5500 in, needs a tcm (soon as the engine warms up it shuts itself down and loses communication, swapped another tcm in after repairing some green wiring...)
I believe the TCM is an a50 (LMM engine) but I'm not positive.
My question... Can I completely program a new TCM from the dealer with my v2?
Thanks!

Sent from my flashscan v2
Hi all, I got the new TCM in, OS is a different version than the old TCM. I have saved copies of the old TCM file, the new one blank and a modified version I attempted to build using the parameters from the old, along with the base file from the new blank (AC delco from the dealer). Anyone willing to take a look at what I have and see if you can make a file that works? Flashing appears successful but I still don't have scan tool communication, I have a flashing service light and an active u0101 code in the engine. I am at whits end with this thing and I'd rather not send it to the dealer.
Thanks!
Will
You will need to program it with dealer programming
