Symptoms of Transmission Problems

Early warning signs may help you avoid costly repair bills and significant safety issues.

The transmission is a critical part of your vehicle's drive system. Transmission failure typically means the car can't be driven until the transmission is fixed or replaced. Both manual and automatic transmissions share many of the same trouble signs that signal transmission problems or failure. Being alert to early warning signs may help you avoid costly repair bills and significant safety issues.

Rough Shifting

Abrupt or hard shifting between gears is the most common sign of transmission problems.

Fluid

Dark or dirty transmission fluid is another key to potential transmission problems, but it doesn't necessarily signal imminent doom.

Leaks

Small stains or drops of fluid beneath the vehicle may not be a problem, but wet spots and puddles deserve immediate attention. Running your vehicle with low or no transmission fluid is a sure way to end up with a new transmission.

Sounds

A rhythmic, heavy-knocking sound can indicate transmission problems. Grinding when shifting gears is another indication of problems.

'Slippage'

"Slippage" is when the engine speeds up but the vehicle doesn't respond accordingly. It is a sign of a failing transmission.

Missed Shifts

A delayed or missing response when shifting gears is a sure sign that your transmission has failed or is failing.
