W5500 LLY / Ally - TCM

[Boost]

There is full support only for the applications on the list, I get that. But out of curiosity I read and saved the TCM cal from a tow truck we are trying to fix at work. It is an '06 GMC flatbed, with a VIN "2" engine and a 5 speed Allison. The TCM box says A46, but it looks like an A40 and the actual module says model A40. The E35A was detected automatically but I had to manually select the A40 (the AL5 also showed a green check for communication BTW). I pulled and saved the cal. just fine, it has a bunch of question marks for the VIN but I think that's normal, (VCI cal. from GM is what goes in these trucks). The problem is I need to block a "phantom" U1000 code that is causing limp mode, but Trans. Diag. settings are not available. Only performance parameters are adjustable. Is there anything else I can try to be able to block DTCs reported by the TCM? Here is the file: (will post in a few minutes)

Well, I have since realized that the Ally TCM does not store codes like the gasser TCMs. So there is perhaps nothing wrong with the functionality of it and I'll have to customize the diagnostics for the tranny from the E35A ECM. But here it is anyway:

Update:

It appears the problem is solved for mow, thanks to the scanning and diagnostic capability of EFILive we were able to pinpoint the issue and solve it without even flashing.

Still it was nice having multiple options. Perhaps the 5500 should be added to the support list? It seemed to work just fine.
