BMW E46 M3 6-Speed Manual Shifter Rebuild & Refresh Kit – Gear Selector/Shift Linkage Bushings Upgrade | Poly Rear Carrier Mount + PTFE Bushes | Gear Lever Wobble/Play Fix – ECS Tuning + Turner Motorsport

Transform your E46 M3 gear change

Tired of a vague gear stick and rubbery engagement on your BMW E46 M3? This complete gear selector refresh package tightens the entire change mechanism for crisp, precise, confidence-inspiring shifts. By combining premium PTFE bushings with a polyurethane rear carrier mount, it removes unwanted free play in the linkage, sharpens both lateral and fore‑aft movement, and restores that satisfying, positive notch into every gear.

Why enthusiasts choose this upgrade

• Eliminates side-to-side wobble at the gear lever for a tighter, more accurate gearchange
• Upgraded materials outlast tired factory rubber and maintain precision under heat and hard driving
• Reduces slop in the selector assembly and improves shift feel on fast road and track
• OE-plus refresh with performance-focused components for a factory-fresh yet sportier engagement

What is included

• PTFE shifter bush set to tighten the selector pivot and linkage interfaces
• Turner Motorsport polyurethane rear shift arm bushing to stabilise the carrier and resist deflection
• Replacement hardware and clips for a thorough rebuild
• Dowel pin for the linkage joint
• Rubber boot to seal the transmission tunnel and keep noise and heat down

Real‑world results

We run this setup on our own cars and it is a night-and-day improvement. Customers consistently report a more direct gear selector, reduced play in the linkage, and a cleaner, more engaging shift action that makes every drive feel special.

Perfect for

• BMW E46 M3 owners looking to refresh a tired gear linkage
• Drivers wanting a precise, positive gear change without going to a short shift kit
• Fast road, track day and spirited driving where accuracy matters
