Buying Guide
What to consider when choosing an automatic floor shifter kit
- Transmission compatibility: Confirm the kit’s listed transmissions (GM TH400, TH350, TH200, 700R4, etc.) match your current setup. Some kits exclude certain models.
- Shift mechanism and mode: Decide between standard detent shifts, ratchet modes, or both. Ratchet modes can aid performance driving or racing but may feel different for daily driving.
- Mounting and fit: Check whether the kit mounts directly to the transmission or requires a console modification. Ensure shaft length and reach match your cab or interior layout.
- Controls and safety: Look for models with neutral safety switches, reverse lights, and lock-out features that reduce mis-shifts or accidental gear changes.
- Quality and durability: Metal construction, corrosion resistance, and thread durability affect longevity in internal and exterior environments.
- Interiors and aesthetics: Choose a shift stick length and knob style that aligns with your vehicle’s interior theme and driver ergonomics.
- Installation considerations: Some kits require trimming consoles or modifying cable runs. Plan for potential wiring and bracket needs.
