Upgrade your Subaru’s interior and shifting precision with the Billetworkz CVT Shift Knob Adapter—engineered to integrate seamlessly with most factory automatic CVT shifter assemblies.
This precision-machined adapter replaces the factory shift knob button with our custom spring-loaded pull-up lockout system. Unlike other designs that require lifting or pressing on the entire knob—our fixed-position setup keeps your knob secure, eliminates rattles, and delivers a clean, confident shifting feel.
To engage reverse or drive, simply lift the lockout collar. The spring-loaded mechanism automatically resets into position, preventing accidental shifts and maintaining a sleek, factory-plus appearance.
- Fixed-position lockout system prevents unwanted movement or rattling
- Spring-loaded collar for smooth, deliberate gear engagement
- CNC-machined from high-grade 6061 aluminum
- Durable anodized finish in Black, Red, Blue, or Orange
- Compatible with all Billetworkz shift knobs (M12x1.25mm thread)
(Compatibility with other brands not guaranteed)
Fitment Note:
Before adding to cart, please select whether your vehicle has a factory shift boot.
- Vehicles with a shift boot will have a leather or synthetic sleeve surrounding the shift lever.

Compatible with Subaru CVT-equipped automatic models using factory push-button shifter assemblies.

CNC-Machined Billet Construction
Crafted from high-quality 6061 aluminum for durability, strength, and a premium feel. Designed to let you install any Billetworkz shift knob on your automatic or CVT vehicle with a perfect, OEM-level fit.
CVT shift knob adapter praised for superior feel and quality over stock. Customers said it's "far more substantial than the factory shift selector" with easy installation taking under 15 minutes. Most love the customization and improved driving experience. Some report screws loosening over time, requiring retightening or Loctite. A few experienced attachment issues.

Arthur Nolle Upgraded my 21 CT Limited shifter in about 10 minutes with the Billetworkz CVT adapter kit and it looks so clean with no loss of function. Watch the BW installation vids on YT. Lifting the lockout ring takes me back to my WRX days, almost. Buy it. you will not be disappointed.

Package came in on time. Everything looked great. Installing it was super easy with the help of youtube videos. I've had mine for about a week and it feels smooth when changing gears.

I absolutely adore this shift knob! It has a more race-like appearance compared to the stock one. The installation process was incredibly straightforward. I managed to change the shift knob in just about 5 minutes. This upgrade has given me a renewed sense of excitement and enthusiasm for driving on the road!

Great converter.
I love that it comes in different colors. The only thing that a make it better is if there is a carbon fiber version.

This sphere is beautiful. It coordinates perfectly with the red accents of my WRX. It looks much better than the OEM shift knob. The product has a good weight, the finish is perfectly smooth, the color is vibrant, and the Auto CVT Adaptor appears to be excellent quality. This is a beautiful addition to your vehicle's interior.

These idiots had the nerve to diss via email over my honest review. I've submitted a request wanting a phone call from a supervisor but have yet to receive one. Come on guys. You wanted the smoke so let's go. Their exact words were "Faulting us is like going into an Italian Restaurant and being upset that they don't serve sushi" in which the reference can't even be applied to my situation. Again, your shift adapters are made to work directly with your shift knobs made by Billetworkz but you guys do say that others may fit. I wasn't feeling the designs of the shift knobs available from Billetworkz and prefer an all black carbon fiber (sphere) shift knob with a red pinstripe running horizontally across it. They had nothing like this. But since the shift adapter's tip fits the size M12, I was hoping it would fit my application. So, I ordered the shift adapter to give it a shot. It didn't work out for me and so I packed up the part and shipped it back for a return/refund. A few days later, I decided to give these bastards a review. I wasn't being snotty. I was just being honest. I said that their shift adapter was sturdy and was built with great mechanism, however it just didn't suit my needs due to my own shift knob (size M12) didn't fit their shift adapter. So there it is. This is when their reviews team replied to my review via email being a bunch of smart asses. Well, let me say this again then. Faulting a customer for being honest is like getting mad at someone for paying your bills. Customers are the ones running your company you idiots. Smh. I hope whoever sent me that email responds back to me. Otherwise, they can go and shove that shift adapter up where the sun don't shine. Good day.

I love the pull up to switch gears. I hated the OEM button. I sometimes wouldn't be completely in Reverse with the OEM shifter. This adapter I know I'm fully in Reverse.
