P0748 code
Me again.
2004 Silverado 2500 HD with Duramax and Allison trans. It's started throwing a P0748 code and seems to be in limp home mode. I can clear the code and it will be ok for about a minute then comes right back. P0748 is Pressure Control Solenoid A, and my research tells me to look for bad connections, broken wires and such. Anybody happen to know where this thing is located, or have any additional thoughts? TIA - K
