Tccm interchange info needed for 12577412 can I use 157...
I have a 2000 Jimmy with NV236 tcase it's giving C0308 and U1026 codes and my fuse (under hood has been blowing) it has a 12577412 tccm can I swap it with a 15748800 tccm? Did the 125xxxx tccm also supersede- replace the 150xxxxx tccm? What happens if you use the wrong tccm an can you have it reprogred to work.
Also I have continuity to ground at the black 4 pin tccm plug to both black wires and the red, and 12v at the orange wire is that normal?
