1997 Ford F-150 Repair Question
1997 Ford F150 Slip or Hesitation before trans engages
1997 Ford F150 6 cyl Two Wheel Drive Automatic 81000 miles
My 97 F150 will hesitate momentarily before engaging first gear. It then will drive fine. I had the fluid level checked, it was full. Had a service, new fluid and filter, still acting up. Changed the internal solinoids on the valve body because mechanic told me it was giving the code for a bad soliniod. It will work fine with NO problems if you manualy shift it into first.
I am at a loss. Local dealership has no or will not give any advice.
Lack of acceleration,chugging,hesitating,bogging etc. could be caused by one of the following below:
Possibilities: Inspect and test all the following listed below:
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Manifold absolute pressure sensor.
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.
Note:If it doesn't apply disregard it.
