3 Signs You Need a Transmission Service at Your Genesis Dealership

Transmission Fluid Leak

Transmission fluid circulates through the transmission, protecting components against friction damage by covering them with a friction-resistant coating. It also provides the hydraulic power that allows the gears to shift. The transmission is sealed, but if it’s not regularly serviced, the transmission pan gasket at the base of the unit can crack, and the fluid will leak.

A fluid leak is easy to see, as it’s bright or dark red depending on its age. If you have a transmission leak, we advise against driving, as a low fluid level will cause the transmission to overheat and potentially seize and need replacement. Even driving a short distance will increase wear and tear on transmission components. We’ll replace the damaged seal and refill the fluid.

Buzzing or Humming Noises

This issue starts with a very slight buzzing or humming sound that’s often overlooked. As time passes, the sounds will become louder, and this is a sign of trouble. The most common cause of these odd noises is low transmission fluid, but they could also be due to worn gears, damaged bearings, a fault with the transmission pump that pushes the fluid through the system, or something else.

Sometimes the buzzing or humming noise will morph into a whining sound, and this usually means an issue with the torque converter. The torque converter is the section of the transmission that connects the engine and transmission. Whining sounds can mean worn stator support bearings, a damaged torque converter clutch, or a failing torque converter. We’ll investigate and repair the problem.

Slow Shifting

As you increase or decrease speed, the transmission control unit sends instructions to the gears, and they automatically shift up or down depending on your speed. Gear shifting is quick, and you won’t really notice it. Slow shifting is an obvious delay between gear changes that results in a drop in power, and you’ll probably hear a revving noise from the engine.

Like many transmission issues, it can be due to low fluid, but it could also be due to damaged gears, broken transmission bands, a failed sensor, or a faulty transmission control unit. We investigate and fix the problem.
