The Importance of the Transmission

Your transmission is a unit that, through a series of shafts and gears, connects the power that is produced by an engine to the wheels. There are two main types of transmissions, automatic transmissions, and manual transmissions. Automatic transmissions are capable of changing gears without driver input, while manual transmissions require the driver to change gears during acceleration and deceleration. There are many different types of manual and automatic transmissions available on the market, each type with its own set of uses.

Transmission Inspection Services

It is important to make sure that your transmission is operating properly. Because transmissions have many moving parts, it is easy for the transmission to become damaged after some time. Manual and automatic transmissions operate differently and have to be maintained differently as a result. With manual transmissions, the most common part that needs to be maintained routinely is the clutch. In the case of automatic transmissions, drivers should mainly be concerned about the conditions of the transmission fluid and torque converter.

Transmission Fluid Exchange Services

Manual and automatic transmissions both have transmission fluid in them. The fluid keeps the transmission clean, cool, and adequately lubricated. However, over time, the transmission fluid gathers an increasing amount of debris and needs to be replaced. Dirty transmission fluid cannot lubricate and cool the transmission, ultimately leading to more problems for the transmission. We offer transmission fluid exchange services at Happy Hyundai, replacing old transmission fluid with fresh new fluid.

Transmission Replacement Services

A damaged transmission can prevent a car from moving entirely and will need to be replaced in order to get a car back on the road. Grinding noises, inability to change gears, leaking transmission fluid and a burning smell coming from the transmission are all signs that the transmission is having issues. While we hope that our customers do not have serious transmission problems, we offer transmission replacement services for when they are needed. We replace all of the parts in your engine with genuine original parts from Hyundai.
