Billetworkz Automatic Shifter

2019+ Toyota GR Corolla Hatch Sedan

Part #: BW-KNB-GRAUTO-NO-REDBS-SL-RED

Overview

Upgrade your Toyota GR Corolla or Corolla Hatch/Sedan interior with the Billetworkz Automatic Shifter in Red Black Splash. This premium shift knob and lockout system is a direct replacement for your factory automatic shift knob, designed to elevate both the aesthetics and functionality of your vehicle’s interior. Ideal for enthusiasts seeking a more engaging and performance-oriented driving experience, this shifter delivers crisp, mechanical engagement with a refined feel that enhances control and safety.

Unlike traditional automatic shifters that rely on a push-button to change gears, the Billetworkz system features a custom push-down lockout collar. This innovative design allows you to engage gears by simply pushing down on the collar, while the knob itself remains fixed in place. The result is a rattle-free, solid connection that resets instantly after each shift, providing confidence and precision during spirited driving or daily use.

Construction & Design

The Billetworkz Automatic Shifter is meticulously crafted from premium 6061 aluminum, known for its excellent strength-to-weight ratio and corrosion resistance. Each component is CNC-machined to exacting tolerances, ensuring a perfect fit and smooth operation. The shift knob undergoes a multi-step polishing process to achieve a mirror-like finish before being hand-anodized using an intensive process that creates vibrant, multi-color effects while providing a durable, scratch-resistant coating.

The lockout mechanism is engineered to replace the factory shift button with a push-down collar that remains firmly in place during gear changes. This design not only improves tactile feedback but also enhances safety by preventing accidental shifts. The entire assembly is designed to deliver a refined, rattle-free feel that complements the sporty character of the Toyota GR Corolla.
