Several problems with a Ford truck's day-to-day operation can be attributed to failures within its transmission system. Some minor issues are fixable on a do-it-yourself basis, whereas more serious problems may need the attention of a qualified mechanic.

  • If the truck refuses to go into gear, motorists are encouraged to check their transmission fluid levels. Transmission fluid provides the mechanism with essential lubricant, without which it will not work correctly.
  • If there is a delay before the truck switches gears, or if the gear changes are erratic, the problem may be a broken vacuum line or a worn-out clutch assembly.

Modern truck transmissions are kept on track via a collection of solenoids and electrical sensors, which reside inside the transmission. Solenoid or sensor problems can manifest themselves in several ways.

  • The truck's check engine light is illuminated.
  • The truck's speedometer no longer works.
  • Instead of slipping into neutral, the vehicle remains in a single gear, regardless of speed.
  • The truck feels underpowered as it accelerates.

When any of these symptoms occur, error codes drawn from the vehicle's computer can help pinpoint the faulty solenoid.
