2003 Ford F150 Lariat SuperCrew 4x4 5.4L 4R70W unique loss of 3-4 gears
2003 Ford F150 Lariat SuperCrew 4x4 5.4L 4R70W unique loss of 3-4 gears.
I lost my 3-4 gears and now while in OD it neutrals when trying to Shift to 3rd, with OD OFF- it remains in 2nd gear w/ no engine braking. When in 1 it stays in 1 in 2 it starts and stays in 2 both with engine braking. My questions are:
P0402-EGR Flow Excessive.
P1401-DPFE Sensor Circuit High Voltage Detected.
P0441-Evaporative Emissions Control System Incorrect Purge.
P0481-Cooling Fan 2 Control Circuit Fault.
C0401-Chasis SAE Aux Emissions Control Fault (EVAP).
P0010- (was also a frequently repeated code) Intake Camshaft Position 'A' Actuator Circuit Open Bank 1.
P0501-Vehicle Speed Sensor 'A' Range/Performance.
P0601-Control Module RAM or ROM check-sum error.
P2802-Transmission Range Sensor 'B' Circuit Low.
P0757-Transmission Shift/Timing Solenoid Malfunction/3-2 Shift Solenoid.
P0C01-AT Transmission 3-4 Shift Solenoid & 'B' Actuator Malfunction or Low Input Signal/Powertrain Crankshaft Position Sensor 'A' Circuit Low Input.
P0802-Transmission Control Module MIL Request Circuit.
P0004-Fuel Volume Regulator Control Circuit High.
P0800-Transfer Case Control System (MIL Request).
Cleaned out EGR Valve and Vacuum Lines and reset ECM, Scanned again and Not one Code has been shown. It's been over a month.
Please give me another option besides a full rebuild or atleast some hope that it's something simpler that I can diagnose first! Thanks guys.
I lost my 3-4 gears and now while in OD it neutrals when trying to Shift to 3rd, with OD OFF- it remains in 2nd gear w/ no engine braking. When in 1 it stays in 1 in 2 it starts and stays in 2 both with engine braking. My questions are:
- is it at all possible that it is something(anything) other than my Forward/Direct drum?
- Should I check the Servos, Accumulators, Solenoids etc?
- Would a TransGo shift kit help or is it a waste of money and time?
- Neutral in 3rd wont shift to 4th.
- No noises or grinding or anything noticeable, it just went out.
- Have 60k on rebuilt tranny 3yrs 6 Mo ago that has never been driven hard has always been maintained and doesn't tow anything.
- Fluid level and color/smell is like new.
- Had DTC Codes flash all within 10days.
