2011+ TCM Full flashing

[rcr1978]

Has anyone tried to full flash a 2011 up TCM (T14) with EFILive yet? The TCM in my truck is intermittently taking a vacation verified with a replacement from a identical truck thought it was wiring at first then traded TCM's with another truck and the problems followed the TCM. I'm not wanting to go through the dealer for the flash of the new TCM and wanting to use my EFILive software and I have a stock TCM read from the truck before the problems started so the proper vin# will actually get flashed back in for the TCM. Also can A50, A51, & A52 TCM's be used in place of the T14 with the proper flash?

Thanks
Robert

Just in case anyone want's to know I put the A50 out of my 2010 and Full flashed it for the 2011 so a A50 will work in place of the T14 TCM. Only thing is the vin# did not change from the 2010 truck I took the TCM out of so hopefully this can be fixed when we get A50 tuning support. I wonder why they call the new TCM a T14 when it's just a A50 or at least that's what EFILive's software sais?

Robert, the TCM models A51, A52 and T14 are all news to me

The external appearance is the same on all of them I just didn't know if there was any hardware differences or not.

That makes two of us
If they are standard replacement TCM's via GM spares for the same model year truck then they are probably 100% compatible.

Another update found that I could program the vin through the old V7.5 scan tool software.

The T14 has been around for a while now, I believe it replaced the A50. 2010 I think but not 100%.

So has anyone tried to full flash a 2011+ tcm with the early lmm programming?

Will not work

Has there been updates on lml tcm programming? I thought I read about it being in beta testing. Any idea on possible release dates if that is accurate?
