Transmission Range Selector Switch ⚙️

This OEM-grade gear position switch tells the vehicle electronics exactly which gear you choose on the shift lever (P–R–N–D). It talks to the ECU/TCM, controls the starter interlock, and triggers the reverse lamps. Built for harsh underbody conditions, it uses sealed contacts for clean, accurate signals and long life.

Why this part is needed

Accurate gear data keeps the automatic transmission shifting smooth, protects the gearbox, and ensures the engine only starts in Park or Neutral. It is a key safety and drivability component.

How it works

Inside, a rotary contact plate and fixed terminals align as you move the shifter. The switch outputs a coded signal so the control module knows the exact range. It also routes power to the reverse light circuit. Simple, reliable, and precise.

What happens if it fails

Hard or delayed shifts, wrong gear shown on the dash, no-start in Park/Neutral, stuck in limp mode, or no reverse lights. You may see a check lamp and stored TCM codes. Moisture, wear, or misalignment are common causes.

Tech notes ✅

Check harness and mounting before replacement. After install, align per marks and clear codes. A quick range-learn procedure may be required.
