25psi...... should be around 60. replaced fuel pump and filter, now truck runs great.
......however:
transmission will not shift.
have the following codes for the transmission:
P1747 refers to a transmission issue.
The PCM has detected
a malfunction within the EPC
(Electronic Pressure Circuit) circuit.
P0750 indicates a malfunction
for a transmission shift solenoid.
p0755
indicates that there is a problem with the
transmission's shift solenoid B
p0743
Low transmission fluid level
Faulty Torque Converter Clutch (TCC) Solenoid
transmission fluid is where it should be. i think i have a power delivery issue to the transmission itself, hince all the codes. Transmission was fine when i pulled it from the mountaineer.
I unplugged the transmission plug on the right side of the trans, and that caused the O/D light to blink, so i think im getting power there.
Can't manually shift from 1st to 2nd either. just sits in 1st.
