Where is the best place to obtain a stock Allison transmission tune file for LML with OS: 24259875 Calibration: 24270404?

does it work to pull the TCM file off the truck thru the OB2 port even though it doesn't work to pull the ECM file off?

I don't believe the TCM is locked up like the ECM. that really is the best place to get the stock tune

ok thank you for the reply, I haven't tried pulling the TCM file yet assuming it was going to be the same thing. i will give it a shot when i have access to the truck
