Learn how the Billetworkz CVT Shift Knob Adapter fits 2019-2024 Subaru Foresters, including installation steps and thread compatibility.
Quick answer
The Billetworkz CVT Shift Knob Adapter fits 2019-2024 Subaru Foresters with factory automatic CVT shifter assemblies, replacing the stock button with a spring-loaded pull-up lockout for better ergonomics.
Why the Billetworkz adapter fits your Forester
The Billetworkz adapter is CNC-machined from aluminum and designed specifically for Subaru CVT shifters. Unlike universal adapters that require lifting or pressing the entire knob, its spring-loaded pull-up lockout integrates with the factory button assembly, making installation straightforward.
One tradeoff: the adapter is color-customizable but does not include a shift boot or knob. You will need to reuse your existing knob or purchase one separately.
Installation steps
- Remove the factory shift knob: Grip the existing knob firmly and pull straight upward. Most Subaru CVT knobs pop off with moderate force. If stuck, use a plastic pry tool to avoid scratching the shifter base. Do not twist the knob—it is held by friction clips, not threads.
- Detach the factory button assembly: Locate the small release tab on the underside of the shifter handle. Press it with a flathead screwdriver to release the button unit. Slide the button assembly out from the top. The button assembly is fragile; avoid bending the plastic clips.
- Install the Billetworkz adapter: Align the adapter's lockout mechanism with the shifter slot. Press it down until the spring-loaded latch clicks into place. The adapter should sit flush with the shifter surface. If the adapter does not click, check that the lockout pin is fully compressed before seating.
- Reattach the shift knob: Slide your chosen shift knob over the adapter until it snaps onto the locking ring. Test the pull-up action: the knob should lift about 1/4 inch before the shifter moves. A loose knob indicates the locking ring is not fully engaged—remove and reseat.
- Test the lockout and shift pattern: With the vehicle on and foot on the brake, pull up on the knob and move through P-R-N-D. Release the knob to confirm it locks in each position. The lockout must engage before shifting; if the knob moves without pulling, the adapter is not seated correctly.
