Transmission Shift Relay – Essential Power for Smooth Gear Changes ⚙️

Why Is This Part Important?

This relay is a small but critical component in the automatic transmission system. It acts as a switch, allowing the vehicle's computer to send electrical signals that control gear shifting. Without this relay, your car can't smoothly manage gear changes, risking both driving comfort and safety.

How Does It Work?

The relay receives low-voltage signals from the car's computer and safely converts them into higher power needed by the transmission solenoids. When the driver accelerates, shifts gears, or uses cruise control, this relay ensures fast, accurate transmission responses.

What Happens If the Relay Fails?

• Unexpected gear slipping or hard shifting
• Transmission stuck in one gear
• Check engine light (CEL) turns on
• Poor fuel economy
• Potential damage to transmission system
