Interesting. GM Cal ID checking tool lists that as the correct OS. It also shows an alternate fuels ECU for this VIN. Is the vehicle natural gas or propane fueled??

CNG tunes are not supported by TC, EFI, or HPT. With the P01 and P59 PCMs the OS would begin with a "5" for CNG applications. The Blackbox OS still begins with a "9" in CNG applications.
Yeah I have a cng file 2005 6.0 that was switchable from gasoline to cng. I thought it would be a cool possible switchable tune deal. I could never open it on any suite in hex it was one goofy looking calibration.
OK, going forward, ... flashing a gasoline file into the K3500 PCM.
Attached is a .cal file I came up searching Auto Trader for a VIN #.
My question: Is the transmission type identified in the VIN#?
Original VIN # 1GTHK33R0YF450300 / Alternate VIN # 1GBJK34R8YF466801
Thanks,

The VIN decoders list both VINs as HD 4 spd auto or HD 5 spd manual. When I get home I can look at tables to see if they look reasonable for an auto trans.
I can provide a VIN from a 2000 HD K2500, 5.7, 4L80E today. If you can wait until tomorrow I can provide a calibration from the same vehicle.
