Standard Ignition SC601 Automatic Transmission Output Shaft Speed Sensor

Automatic Transmission Output Shaft Speed Sensor

Standard Ignition SC601 is an automatic transmission output shaft speed sensor built for vehicles that rely on accurate transmission speed feedback. It uses a bolt-mount design with a rectangular female plug-in connector, a 2-wire harness, and male blade terminals for a direct electrical connection.

Compatible with Volkswagen Beetle, Tiguan, CC, Jetta, Passat, and Audi TT applications, this sensor supports transmission signal monitoring on a wide range of late-model import vehicles. The SC601 part number is also a direct reference for service matching when replacing a failed output shaft speed sensor.

Key Features

• Bolt-mount attachment with one mounting hole
• Rectangular female connector with plug-in style connection
• 2-wire design with male blade terminals
• Wiring harness included for installation support
• Black and grey finish
• Standard Ignition SC601 replacement sensor

Detailed Description

The Standard Ignition SC601 automatic transmission output shaft speed sensor monitors transmission output shaft speed and sends the signal needed for proper transmission control. Accurate speed input is important for shift timing, drivability, and transmission system operation. This sensor is a practical replacement for Volkswagen Beetle, Volkswagen Tiguan, Volkswagen CC, Volkswagen Jetta, Volkswagen Passat, and Audi TT models listed in the fitment data. This part cross-references Walker Products 240-1143 for the same application.

What It Helps Address

• Erratic or delayed transmission shifting
• Speed signal loss from a failing output shaft speed sensor
• Transmission warning lights related to sensor input
• Harsh or inconsistent shift behavior
• Drivability issues tied to incorrect transmission speed data

Installation Notes and Tips

• Verify connector style, mounting type, and wire count before installation.
• Inspect the transmission connector and harness for corrosion, bent terminals, or damaged wiring.
• Confirm the sensor seats fully at the bolt-mount location and the connector locks in place.
• Use the vehicle fitment list to match the correct Volkswagen Beetle, Tiguan, CC, Jetta, Passat, or Audi TT application.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and engine management components. SC601 is built to match the listed OE-style application requirements for the specified vehicles.
