Automatic Transmission Output Shaft Speed Sensor

Standard Ignition SC377 is an automatic transmission output shaft speed sensor built for direct-fit service on select Acura RL applications. It uses a bolt-mount design with a rectangular plug-in connector and 3 blade terminals for a clean OE-style connection.

Fits 1996-2004 Acura RL, N/A. This part cross-references Standard Ignition SC377 for the same application.

Key Features

  • Automatic transmission output shaft speed sensor for transmission speed signal monitoring
  • Bolt-mount attachment with 2 mounting holes
  • Female rectangular connector, plug-in type
  • 3 male blade terminals
  • Silver and black finish
  • No wiring harness, mounting bracket, or hardware included

Product Details

SC377 is designed for vehicles that rely on an output shaft speed signal to support transmission control and drivability. On 1996-2004 Acura RL models, this sensor helps the transmission control system read output shaft speed for shifting and related calculations. The Standard Ignition SC377 follows the listed connector, terminal, and mounting configuration for straightforward replacement service.

For buyers searching for an Acura RL transmission speed sensor, Acura RL output shaft speed sensor, or Standard Ignition SC377 replacement, this part matches the specified OE-style layout and electrical interface.

Common Issues It May Address

  • Erratic or missing transmission speed signal
  • Harsh, delayed, or inconsistent shifting
  • Transmission warning light related to speed sensor input
  • Speedometer or transmission control concerns tied to output shaft speed data

Installation Notes

Verify connector shape, terminal count, and bolt-mount location before installation. Inspect the mating connector and transmission case opening for damage or contamination, and confirm the sensor seats fully against the mounting surface. Because no wiring harness or hardware is included, reuse or source any required vehicle-specific components separately.

Quality Assurance

Standard Ignition replacement sensors are built to match the listed application details for fit and electrical connection. Confirm vehicle year and model against the fitment data before ordering.
