Car jumping when you put it in gear to park

Question edited into written English.
Question moved to model category.

It sounds like you have and unusual and flawed driving technique.

Manual or Automatic?

Automatic. You never use neutral unless you are in a car wash that drags your car by the wheels. Decelerate, foot on the brake and into Park. Your right foot does both brake and accelerator, left foot does nothing. I saw a lady 2 days ago with left foot on the brake and right foot on the accelerator.

Manual. Downshift through the gears, right foot on the brake, left foot on the clutch and into neutral and hand brake on.

If you are doing that, the vehicle needs diagnosis why it is happening.

you need to have your foot on the brake pedal and be holding the pedal down. its a safety feature to keep you from accidentally driving away.

If it is locked in park, it could be the brake switch or the shift lock solenoid. You may be able to shift out of park before you turn the key switch to the on position.

Ok, let me see if i understand your question. It must be that you want to engage a different gear but since your car is dead then it will not allow you to shift to another gear without the car being on. If that is the problem that you are trying to move the vehicle by pushing it or something like that then let me say that fords have a an electric plunger on the foot brake that actuates the shift mechanism. The battery must be somewhat charged enough to engage this by placing the key in the courtesy setting (turn key just before the engine turns over) But since your engine is dead I will asume that you dont have any juice on the battery, If so let me know if this helped you. Once you have juice in the battery then depress the brake and the shift column should move freely after that. G.E.

Has Coke or anything that goes sticky been spit around gear shift? I have had this before & had to pull console apart & clean with spray & wipe.

hi u might have a problem in the power steering pump and its loading up the motor through the drive belts.it would pay to have it checked good luck

WHEN YOU DISCONNECT THE BATTERY THE ENGINE MANAGEMENT SYSTEMS PCM LOSES IT MEMORY INCLUDING ENGINE IDLING.THE COMPUTER WILL HAVE TO RELEARN THE OPERATING VALUES. IF CAR DOES A LOT OF STALLING AT STOP LIGHTS AND STOP SIGNS. GO BY FORD DEALERSHIP LET THEM REPROGRAM THE PCM.PROBABLY CHARGE YOU $35.00 DOLLARS. TO REPROGRAM PCM.

Have you found a solution to this problem yet? My '07 model is doing the same thing! Thanks.

You might want to go to a electrical shop to have your car hooked up and have it tested for either a short or a loose or bad wire or connection.
