2. TH350 Transmission Shifter for GM Turbo 350 Automatic Transmissions Complete 12″ Stick
When I first came across the TH350 Transmission Shifter for GM Turbo 350 Automatic Transmissions, I was immediately drawn to its purpose-built design and robust features. This product is clearly tailored for enthusiasts and mechanics who want a reliable and high-quality shifter specifically for the GM Turbo 350 automatic transmission. Knowing that it’s a complete 12″ stick gives me confidence that the length and style will provide an excellent balance of comfort and control, especially if you’re looking to upgrade or replace your existing shifter with something more substantial and visually appealing.
One of the standout features for me is the 12″ chrome shifter arm. Chrome not only adds a sleek and polished look that enhances the interior aesthetics of your vehicle, but it also suggests durability and resistance to wear over time. This is important because a shifter is a frequently used component, and having one that holds up both visually and functionally is a significant advantage. I appreciate that this product doesn’t just focus on looks but also on safety and reliability, as evidenced by the gated lock-out safety feature. This ensures that accidental shifts are minimized, adding an extra layer of security while driving, which is reassuring for anyone who values safety alongside performance.
It’s also important to note that this shifter mounts directly onto the transmission. This design choice means a more integrated and secure fit, which can translate to improved shifting precision and durability. However, I have to be honest this also means that installation isn’t the simplest task. The note about needing to cut the floorboard and the recommendation for professional installation is something I take seriously. If you’re not experienced with transmission work or custom modifications, trying to install this yourself might lead to frustration or even damage.

3. B&M 80675 StarShifter Automatic Shifter
When I first came across the B&M 80675 StarShifter Automatic Shifter, I was immediately drawn by its promise to give me more control over my vehicle’s automatic transmission. As someone who values both performance and ease of use, this shifter stood out because it lets me manually shift to maximize torque and overall driving performance, yet easily revert to normal automatic operation when I want a relaxed drive. This versatility is a big plus for anyone who wants the best of both worlds without the hassle of complex modifications.
One of the things I appreciate most about this shifter is its versatile mechanism. It can be set up as a straightforward detent shifter, which is great for smooth and predictable gear changes. Alternatively, by lifting the trigger into “Low,” I can switch it to a ratchet action, giving me more precise control over gear engagement. This feature really caters to different driving styles—whether I’m looking for a casual cruise or a more performance-oriented experience. The fact that it includes a backup light switch, neutral safety switch, and NHRA/IHRA reverse lockout shows that the design is thoughtful and prioritizes safety and compliance with racing standards, which is reassuring.
Durability is also a key consideration for me, and the B&M StarShifter does not disappoint. Constructed from a combination of aluminum, steel, and a plastic base, it strikes a good balance between strength and weight. The inclusion of a T-handle and a 5-foot long shifter cable means installation is straightforward and adaptable to various vehicle setups. Plus, the manufacturer backs the automatic shifter (excluding cables) with a limited lifetime warranty, which adds a layer of confidence in its long-term reliability.
Compatibility is often a tricky aspect when upgrading parts, but the B&M 80675 StarShifter covers a wide range of applications. It fits GM TH400, 350, 250, and 200 automatic transmissions, as well as Ford Lincoln and Mercury C4 and C6 transmissions. It also works with Chrysler Torqueflite A727 and A904 transmissions from 1966 onward. This broad compatibility means that if you own a classic muscle car or a vintage vehicle with one of these transmissions, this shifter can be a perfect match. However, it’s important to note that it doesn’t fit TH700R4, TH2004R, or AOD automatic transmissions, and it can’t be used with reverse pattern manual valve bodies—so double-checking your transmission type before purchasing is essential.
To give you a clearer picture, here’s a quick summary of the key features and specs of the B&M 80675 StarShifter
Feature Description Control Options Manual shifting for torque/performance or normal automatic drive Shifter Mechanism Straight line detent or ratchet action via trigger lift in “Low” Safety Features Backup light switch, neutral safety switch, NHRA/IHRA reverse lockout Included Components T-handle and 5′ shifter cable Materials Aluminum, steel, plastic base Warranty Limited lifetime warranty (excluding cables) Transmission Compatibility Fits GM TH400, 350, 250, 200; Ford C4, C6; Chrysler A727, A904 (1966+) Non-Compatible Transmissions TH700R4, TH2004R, AOD, reverse pattern manual valve bodies
In summary, if you want a reliable, versatile, and performance-friendly automatic shifter, the B&M 80675 StarShifter is an excellent choice. It offers an honest blend of manual control and automatic convenience, backed by solid construction and a reputable warranty. While it’s not suitable for every transmission type, for those it fits, it can significantly enhance driving enjoyment and vehicle responsiveness.

Buying Guide for 4L60E Floor Shifter Kit
Understanding the 4L60E Transmission
When I first started looking for a floor shifter kit, I realized how important it was to understand the 4L60E transmission itself. This transmission is widely used in many GM vehicles, known for its reliability and adaptability. Knowing that my vehicle had a 4L60E helped me narrow down the compatible shifter kits.
Why Choose a Floor Shifter Kit?
I wanted to switch from a column shifter to a floor-mounted shifter for better ergonomics and a sportier feel. A floor shifter kit not only improves the driving experience but also enhances the interior look. When shopping, I made sure the kit included all necessary components like the shifter handle, base, linkage, and mounting hardware.
Compatibility with My Vehicle
One of the first things I checked was whether the kit was compatible with my specific vehicle model and year. Even though the 4L60E transmission is common, some kits are designed for particular chassis or floor designs. Verifying compatibility prevented me from buying a kit that wouldn’t fit or require extensive modifications.
Materials and Build Quality
I paid close attention to the materials used in the shifter kit. Durable metals and high-quality plastics ensure longevity and smooth operation. A well-built kit resists wear and tear from frequent shifting, which is important for daily driving or performance use.
Installation Process
Since I planned to install the kit myself, I looked for kits with clear instructions and all necessary hardware included. Some kits require professional installation due to complexity, so I made sure I was comfortable with the steps involved or had access to a mechanic if needed.
Shifter Style and Ergonomics
The shifter’s design affects comfort and usability. I considered whether I wanted a traditional lever, a pistol grip, or a ratchet-style shifter. The handle’s shape and size influenced how it felt in my hand during driving, so I looked at pictures and reviews to find what suited me best.
Adjustability and Linkage Options
Adjustable linkage is a great feature I found useful. It allowed me to fine-tune the shifter’s throw and position for a personalized feel. Some kits come with different linkage lengths or mounting options, which can help accommodate modifications or different transmission setups.
Budget Considerations
Pricing varied widely, so I set a budget before shopping. While I didn’t want to compromise on quality, I also avoided paying for unnecessary extras. Balancing cost with features and durability helped me find a kit that provided good value.
Additional Features to Consider
Some kits include extra features like illuminated shift indicators, custom shift knobs, or enhanced mounting brackets. I considered these add-ons based on my preferences but focused primarily on core functionality and fit.
Final Thoughts
Buying a 4L60E floor shifter kit was a rewarding upgrade for my vehicle. By focusing on compatibility, build quality, and installation ease, I ensured a smooth transition from the original setup. Taking the time to research and assess my needs helped me make an informed decision that improved my driving experience.
