The 2003 Acura RSX Type S features a 6-speed manual transmission with various switches and controls that enhance driving performance and safety. This manual transmission system includes gear position sensors, reverse lockout mechanism, clutch safety switch, and transmission-mounted switches that work in conjunction with the vehicle's electronic systems. Below are key sections covering features, operation, maintenance, and troubleshooting of the transmission switches.
Key components: 6-speed manual transmission, gear position sensors, reverse lockout solenoid, clutch position switch, transmission range switches, and shift linkage components.
| Feature | Description |
|---|---|
| Gear Position Sensor | Detects current gear selection for ECU input |
| Reverse Lockout Solenoid | Prevents accidental engagement of reverse gear |
| Clutch Safety Switch | Requires clutch depression to start engine |
| Transmission Range Switch | Monitors transmission position for vehicle systems |
| Shift Linkage Position Sensor | Tracks shifter position for performance data |
| Back-up Light Switch | Activates reverse lights when in reverse gear |
| Speed Sensor | Monitors transmission output shaft speed |
| Transmission Control Module | Processes switch inputs for vehicle operation |
Understanding the physical locations of transmission switches for maintenance and troubleshooting.
WARNING! Disconnect battery before servicing transmission switches to prevent electrical shorts or accidental vehicle start.
How transmission switches interact with vehicle systems during normal operation.
CAUTION! Never force shift lever - if resistance is felt, check switch operation and linkage alignment.
Driver interface components related to transmission switch operation.
Dashboard Indicators: Reverse gear indicator, check engine light (for transmission-related faults), cruise control disable when clutch depressed.
Shift Mechanism: Reverse lockout collar, positive shift stops, gear position detents. Clutch Pedal: Requires full depression for starting interlock. Gear Position: ECU receives position data for optimal engine performance mapping. Safety Interlocks: Prevents starter operation unless clutch depressed and transmission in neutral.
Routine maintenance and inspection of transmission switches and related components.
Tip: Use dielectric grease on electrical connectors to prevent moisture intrusion and corrosion.
Diagnosing and resolving common transmission switch problems.
WARNING! Always use proper diagnostic equipment - do not bypass safety switches as this creates hazardous driving conditions.
Integrated safety systems controlled by transmission switches.
Clutch Start Safety Switch: Prevents engine starting unless clutch pedal depressed. Reverse Lockout: Mechanical and electronic prevention of accidental reverse engagement. Gear Position Monitoring: ECU uses gear data for stability control and traction management. Cruise Control Disable: Automatically cancels cruise control when clutch is depressed.
Proper care procedures to ensure long-term switch reliability.
Regularly inspect electrical connections for corrosion. Keep shift linkage clean and properly lubricated. Check switch operation during routine maintenance. Protect electrical connectors from moisture and road debris. Use only OEM replacement parts for switch replacement.
CAUTION! Do not use high-pressure spray directly on electrical connectors. Avoid using silicone sprays near switch mechanisms.
Compliance with automotive safety and emissions standards. Meets FMVSS requirements for transmission safety systems. EPA compliant for emissions-related transmission controls. All switches meet SAE and ISO standards for automotive applications. Copyright © 2003 American Honda Motor Co., Inc.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Vehicle won't start | Faulty clutch safety switch | Test switch continuity; adjust or replace switch |
| Reverse lights inoperative | Back-up light switch failure | Check switch operation; test circuit; replace switch |
| Difficulty shifting into reverse | Reverse lockout mechanism stuck | Inspect solenoid; check linkage; lubricate mechanism |
| Check engine light on | Gear position sensor fault | Scan for codes; test sensor; recalibrate or replace |
| Cruise control not engaging | Clutch switch signal missing | Test switch operation; check wiring; replace switch |
| Erratic engine performance | Faulty transmission speed sensor | Test sensor output; inspect wiring; replace sensor |
Reset Procedure: Disconnect battery for 10 minutes to reset transmission adaptive learning after switch replacement.
