Signs of Transmission Trouble

Transmission problems can take several forms. Each symptom may have a number of possible causes, some requiring extensive repairs while others need only an adjustment or minor service.
A systematic checkup by a professional is the best way to isolate the cause of the operating problems and recommend the most effective solution.
Engine Light On–Dashboard light prompts you to “Check Engine” or “Service Engine Soon”
Strange Noises–Makes clicking, knocking, screeching, buzzing, whistling, clanking, or grating noises. Unusual sounds can come from hood or rear of car and may include a hum or low whine.
“Morning Sickness”–When the vehicle is cold, it won’t move, or it shifts late during the first few minutes of operation.
Slipping–Engine races, but vehicle moves slowly or won’t accelerate as it should.
Stalling–Vehicle stalls or labors on take off.
Doesn’t Go–You place the shift lever in Drive and nothing happens. Even racing the engine does nothing.
No Reverse–Vehicle doesn’t move when shift lever is placed in Reverse.
Leaks–Fresh fluid stains under the vehicle.
Loss of Power–Passing gear won’t engage, and there’s no surge of power when you press the pedal to the floor.
Erratic or Improper Shifting–Noticeable early or late shifting. Unexpected shifts, or speed at which shifts occur keeps changing.
Shift Handle Stuck/Sticks–Shift handle is hard to move into or out of any position.
Vehicle Moves (or Jerks) in Park or Neutral
Strange Smell–Burnt or rancid odor is coming from under the hood or underneath vehicle.
Engine Braking/Downshift Doesn’t Work–Using the transmission to slow the car on long downhill slopes or in snow/icy conditions does not work in one or more shifter positions.
Shift Indicator Off–The indicator must be slightly off (P) or (N) to start the car. Shift indicator doesn’t point to the proper range.
Metal Shavings or Debris–Inspection or transmission service reveals excessive amounts of debris in the transmission pan.
