Part number or service number? 'Cause the part number will be a made-up thing based on a specific service number with a specific calibration in it (hardware + software = part number; hardware + nothing = service number). Most times the part number isn't available as a reference anywhere, only the service number.
Its the number thats etched on the TCM. I attached a photo of it. Never seen this number before and nothing is coming up on ACDelco or any GM parts sites i usually use to double check before I try to program them.

Neither number exists anywhere on the intarwebs except for SEO keyword spam sites (a very special thank you to whoever thought up that brilliant idea, BTW).
I've come up with the same results. I'll see if I can reprogram it with SPS. The guy that brought this to me broke his original TCM removing the connector and breaking several pins in the TCM. He then bought this one off of ebay that said it was compatible with the trans he pulled from a '13 silverado but I have never seen this number.Quote:

Awesome! Thanks for the info. I was just coming on here to post that I was able to reprogram the TCM with SPS to the 2013 silverado with that same OS successfully. Engine and trans ran good on my run-on stand with no communication issues after the reprogramming.Quote:
And just an added note for future searches. The current GM part number for the Tchem is 24275873.Quote:

So is it already superseded or just not in the system yet? 2429xxxx is a very high number, that usually gives a clue as to when a part was released.
I am hoping someone can help me with a similar problem. We just finished building a 57 Belair with a supercharged 6.2 managed by a Holley HP. We also added a 6l80 Mad Dog transmission with a PCS TCM 2650 as the controller. That said the transmission came with a new T43 TCM (24275873) and the OS is 24252573 so the transmission is missing a base profile. Does anyone know the year and model of a car using the same OS. Any help would be greatly appreciated.
Searched my files. I got a match (for the OS 24252573) on a 2010 Buick LaCrosse 3.0L w/ the 6T70EQuote:

My experience with "new"out of the box AC Delco TCMs is they are all remanufactured and are expected to be programmed for the vehicle they are going in and can have just about any OS in them out of the box.
tunerpro & 2xLS1..thank you, thank you, thank you.
As I previously mentioned our customer bought a Mad dog stage 2 6l80e w/3000 stall converter. That said, we began by getting the PCS 2650 TCM to communicate with the trans. We then connected with HP in order to verify and tune the trans but unfortunately we encountered the dreaded P0602 DTC. So we did a deeper dive with acdelcotds and got a bit more information. We even pulled the pan to get the GM part number off the TCM. So here we are gathering bits of information so we can get this thing going. I really appreciate your help. I hope to pay it forward in this forum.
Thanks a lot for info!Quote:
