Have you ever seen inside an automatic transmission? These vital vehicle components are wonderfully complex, containing hundreds of parts. They’re also far easier to repair when you catch a fault early. So, here are the key symptoms of a car in need of immediate transmission service at your Toyota dealership.

6 Signs Your Toyota Needs a Transmission Service

Acceleration requires smooth shifting up through the gears. When you step on the gas, if your car revs but seems hesitant to gain speed, your transmission might have low fluid, worn gears, or another problem.

At first, you might just experience a momentary delay of a few seconds before the new gear locks into place and the car finally accelerates. If this happens, have your transmission and its fluid checked before the problem worsens.

Sudden Vehicle Lunging

When transmission fluid is neglected and becomes old or contaminated, lubrication diminishes, and the gearbox starts to act strangely. You might find your car suddenly jolting or lunging when you try to shift gears or even when you’re not shifting gears at all.

Gearbox Slips into Neutral

One of the more hazardous symptoms of a transmission fault is slipping gears. Here, your gearbox might pop suddenly into neutral on its own, robbing the wheels of engine power. Slipping gears can also shift up or down on their own. This kind of serious issue may result from a worn-out clutch or transmission band, rounded-out gears, or a bad solenoid.

Gears Growling Noisily

Poorly lubricated, misaligned, or damaged planetary gear systems can generate growling sounds as the gears struggle against each other. Transmission linkage components can also cause a growling sound, as can worn-out shift forks, bearings, or synchronizer rings. A technician will need to figure out and repair the underlying source of your car’s grinding gears.

Quiet Whining Sounds

While less jarring than metallic growling, quiet whining may also indicate serious transmission trouble. With whining, a blocked line or filter, a bad pump, or low fluid may be causing harm inside the gearbox that will rapidly worsen if not promptly repaired.

Hot Burning Fluid Smell

Transmission faults most commonly stem from low or degrading fluid. This fluid is essential for lubricating, cleaning, and maintaining hydraulic pressure inside the gearbox system.

If your transmission fluid becomes old or contaminated, friction will surge and the gearbox will start to overheat. This starts to burn the remaining fluid, further reducing its volume and exacerbating the problem. If this happens, you’re likely to detect a burning smell from inside the cabin.
