What It Is Used For

• Replacing a failed automatic transmission fluid temperature sensor
• Restoring transmission temperature signal input to the control system
• Addressing temperature-related transmission warning or drivability concerns
• Repairing damaged sensor connectors or harness-side electrical issues
• Supporting accurate transmission fluid temperature monitoring

Installation Notes and Tips

Confirm connector shape, terminal count, and harness length before installation. Match the TX255 to the vehicle application by year, make, and model, and inspect the transmission connector and wiring for corrosion, bent terminals, or heat damage before connecting the new sensor. Because this part uses a plug-in design, proper seating of the connector is important for a stable electrical connection.

Quality Assurance

Standard Ignition supplies replacement electrical and transmission components built to meet service requirements for listed Toyota applications. Verify fitment against the vehicle’s transmission configuration before installation.
