Did everything work out after the new TCM.

Everything was perfect after swapping in the new TCM and having it flashed by the dealer. The dealer actually made me sign something saying that they advised me that flashing the TCM that I just installed would not resolve the issues I was having.. I didn't bother with an "I told you so" but mentioned I am available for consulations as they are obviously in need

Same as Nic. $300 for TCM shipped overnight and $120 to flash it... still a rip off, but j swapped them in like 15 seconds... seems like a scam... why do they fail so often and why do dealer charge so much for a job that a mechanical retard like myself can do in under a minute

2003 duramax diesel TCM Failure HELP

We love our truck and it has been good to us. In Sept 2016 we got in it to come to work and it would not shift out of second. We determined it was the TCM . So we ordered one we were told it would be 2-3 weeks. The time came and went , we were told production issues , another delivery date came and went. We are now being told that GMC does not supply certain parts for vehicles past ten years old. So we are supposed to throw our truck away because of a computer glitch. Have not found any other alternatives.

We need help have filed complaints with Allison since it is made by them, GMAC and so on but so far we are not getting anywhere . Suggestions would be greatly appreciated PLEASE

The early trucks did not have much problem with TCM- The trans speed sensor is in the back of the transfer case, -- the TC would get a leak and burn up the TC. Then the trans lost the speed signal and that affected the shift.

Also a dirty fuel filter would keep the trans from shifting-- would shift if you let off the throttle.

The "flash" costs the dealer money... I'm assuming the dealer pays AC Delco the $3100/yr fee to access the calibration indexes and such. If we were friends, I would charge you the $55 for two-days access, download your unique calibrations to my laptop, and use my Tech 2 in pass-thru mode. So if you think about it, $110/hr shop rate plus whatever portion of the $3100 for yearly dealer access isnt too bad. The dealers are absolutely not a "non-profit service".

A trans reset makes the CEL disappear temporarily, but it returns on the next start after driving.
My 2011 is currently doing the same thing as yours WhiteHD11. Only difference is I have Kory Willis EFI live. Did you end up replacing TCM? If not what can you update us on what happened?

Thanks!
