Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Peugeot 307, Citroën C4
• Product Codes: 9681946280, 2400EK
• Additional Numbers: 2400JX

Function And Purpose

The gear selector gate (shift gate) guides the automatic transmission shift lever through park, reverse, neutral and drive positions. It houses detents, guide bushings and mechanical linkages that translate the driver’s lever movement into accurate cable or rod actuation of the gearbox selector mechanism. Proper operation is essential for safe gear engagement, neutral lock and correct park positioning.

Installation Recommendations

• Prepare: Park on a level surface, apply the handbrake and place the transmission in Park (P).
• Safety: Disconnect the negative battery terminal before starting work to prevent short circuits and accidental gear actuator movement.
• Disassembly: Remove center console trim and shift knob. Unscrew the mounting bolts securing the selector gate and carefully unclip or disconnect the shift cables/rods from the mechanism.
• Fitment: Install the new selector gate in the reverse order. Ensure cables/rods are correctly seated in the detents and that the gate indexing matches the transmission lever positions.
• Adjustment: Check cable end play and adjust if necessary according to manufacturer procedure so that each gear position engages crisply.
• Verification: With the engine off, cycle through all positions to confirm smooth travel and correct locking in Park. After reconnecting the battery, perform a low-speed road test to confirm proper operation under load.
• Tip: Keep fasteners tightened to manufacturer torque values and replace any damaged clips or worn cable ends found during removal.

Common Causes Of Failure

Failures typically result from long-term mechanical wear and contamination. Common issues include worn or cracked plastic guides, fatigued return springs, degraded detent mechanisms, cable end play or stretched shift cables, and corrosion from moisture ingress. Impact damage from improper use or collisions can also deform the gate. Symptoms are excessive play in the lever, difficulty selecting gears, unintended jumping out of gear detents or inability to lock in Park.
