Auto Shop: Is Your Transmission Running?

Understanding Transmission Components

Before diving into diagnostics, it's essential to familiarize yourself with the key parts of a transmission system:

Key Transmission Parts

• Bell Housing: Located beside the engine in front-wheel-drive vehicles and behind the engine in rear-wheel-drive vehicles. It's the bell-shaped part visible when you look under the car.
• Gears: Found in both automatic and manual transmissions, gears are crucial for proper vehicle operation.
• Fluid: Typically red, transmission fluid is vital for lubrication and cooling. A red puddle under your vehicle indicates a transmission fluid leak.
• Filter: This component keeps the fluid clean, ensuring the gears function correctly. It may need periodic cleaning or replacement.

Basic Transmission Checks

Checking Fluid Levels

Regularly checking your transmission fluid levels—ideally twice a year—is crucial. Low fluid levels can lead to poor gear shifting and potential transmission damage. Persistent low fluid levels often indicate a leak.

Common Leak Points

• Base of the filter tube
• Transmission drain hole
• Between the engine and transmission
• Gear shifting rod
• Radiator

Inspecting the Filter

A clogged filter can impede your vehicle's performance. If you suspect a clogged filter, try replacing it before heading to the auto shop.

When to Visit the Auto Shop

If you've checked the fluids and replaced the filter but still experience transmission issues, it might be time for a professional rebuild. Rebuilding a transmission is complex and typically requires a visit to an auto shop. When consulting with your mechanic, provide detailed information about your findings to help them diagnose the issue efficiently.

Cost and Warranty

Rebuilding a transmission can be expensive, but most auto shops offer warranties on rebuilt transmissions, ensuring you won't have to pay for another rebuild for a long time.
