p1747 epc
Its a 1999 f250sd 5.4l auto. Has code p1747. Truck shudders and almost dies when you drop it in gear, put it back in park idles fine. I have read all the post on here about this and checked wires from trans up to pcm look and test good. Tested plug c1048 wires with digital meter to body ground with battery unhooked and got 6.66k ohms on pin 11 circuit 925, 421 ohms pins 1 and 12. Pluged c1048 back to trans checked 925 w/y wire at plug c103 got 9.1 ohms back to trans. Is the epc solenoid bad or is it pcm. I think its epc but want to verify before i take trans apart.
