Types of Transmission

Before we dive into the repair process, it is important to understand the different types of transmission. There are two main types:

Automatic Transmission

An automatic transmission uses a hydraulic system to shift gears automatically. It is more common in newer vehicles and is easier to drive compared to a manual transmission.

Common Transmission Problems

Here are some common signs that your transmission may need repair:

  • Slipping gears
  • Delayed shifting

If your car has a transmission filter, it is recommended to replace it during a transmission repair. The filter helps to keep the transmission fluid clean and free from debris.
