80775 Automatic Shifter Compatible With GM Ford Chrysler
This shifter is designed for broad compatibility across GM, Ford, and Chrysler automatics, making it a versatile option for mixed-fleet garages or older builds. It supports GM TH400, 350, 250, 200, 700R4/4L60, 4L60E, 4L65E, and 4L80E transmissions, with optional bracket kits for certain models. It also covers Ford C4, C5, C6, and AOD families, plus AODE and 4R70W with specific option kits. For Chrysler, it fits 1966 and later Torqueflite A727 and A904. This breadth helps buyers avoid multiple shifters for different transmissions.
Best for: Mixed-vehicle garages or owners replacing multiple transmissions in one project. It includes a shift boot, neutral safety switch, a high-performance 5-foot shift cable, cable bracket, shift lever, and hardware—supporting straightforward installation. It leverages the factory pawl for smooth, non-dampening shifts, which is ideal for drivers seeking consistent behavior across gear changes.
Limitation: Some transmission families require add-on brackets or option kits (e.g., 4L60E/4L65E with PRNDL switch). Confirm compatibility with your exact transmission and required accessory kits before purchasing.
GXYWADY Three and Four Speed Floor Shifter For GM 700R4 TH350 TH400
This replacement shifter targets common GM transmissions: 700R4, TH350, and TH400. It provides a practical option for classic GM builds, offering straightforward replacement for older floor shifters and restoring functionality without an extensive install. It is best for owners who want a reliable, budget-conscious upgrade that keeps a traditional layout while improving operation.
Best for: GM transmission owners seeking a simple, affordable upgrade with compatible 3- and 4-speed setups. It’s a solid choice for restorations or daily-use trucks where authentic shift feel matters.
Limitation: Information on included hardware or exact bracket compatibility is limited in the listing; verify fit with your specific GM model and ensure you have the proper linkage parts for your build.
B&M 80680 Automatic Ratchet Shifter – Light Truck MegaShifter
The MegaShifter is a rugged, ratchet-style shifter designed for light-truck applications. Its ratchet mechanism supports quick, positive gear changes and is favored by drivers who want a sporty feel with strong mechanical feedback. The kit typically includes a complete shifter body, mounting hardware, and the necessary linkage to connect to many automatic transmissions used in light trucks.
Best for: Truck owners who prioritize a robust, performance-oriented shift action and don’t mind a more aggressive shifting feel. It’s a better choice for those who value rapid shifts during off-road or towing scenarios, rather than a traditional, smooth glide between gears.
Caution: Ratchet-style systems may require more frequent adjustments and can be less forgiving on daily city driving compared to detent-type shifters. Confirm fit with your transmission and console opening.
B&M 80775 Automatic Detent Shifter – Unimatic
This Detent Shifter focuses on precise, repeatable gear selections. It uses a detent mechanism to provide tactile feedback at each gear, which helps prevent accidental shifts and improves confidence during aggressive driving or towing. The Unimatic variant is typically designed for compatibility with a range of transmissions and vehicle setups, making it suitable for customized builds.
Best for: Drivers who value precise, repeatable shifts with a clear “lock-in” feel. It’s suitable for performance-oriented trucks and custom builds where cockpit feel and shift accuracy are priorities.
Limitation: The detent mechanism may feel stiffer to new users and could require more deliberate movement than a smooth-pull design. Check whether your console and linkage align with the mounting pattern.
Replacement for B&M 81052 Automatic Gated Shifter Magnum Grip Pro Stick Shifter
This listing targets owners replacing the Magnum Grip Pro Stick Shifter, compatible with 2-, 3-, and 4-speed transmissions. It emphasizes a gated design and robust grip setup, supporting precise control and a more deliberate shift sequence. It’s a practical upgrade for drivers who want a sturdy, positive-shift experience in challenging conditions.
Best for: Builders who already use a B&M gated shifter and want a direct replacement with a similar feel. It’s a good choice for those seeking a strong, high-control option in a rugged truck cabin.
Caution: Ensure your transmission type and console dimensions align with this specific replacement part to avoid fitment issues during installation.
Buying Guide
What should you consider when choosing an automatic floor shifter for a truck?
- Transmission compatibility: Verify which transmissions the shifter supports and whether optional brackets or kits are required for your exact model.
- Shifter action: Decide between detent (positive click) versus ratchet (faster, more mechanical feel). Detent is typically smoother and familiar; ratchet offers a sportier shift.
- Installation scope: Some units come with full hardware and cables, while others require additional components. Consider your ability to install or seek professional help.
- Vehicle usage: For daily drivers, a smooth, reliable shift is key. For performance builds or towing, a decisive, positive shift may be preferable.
- Build quality and materials: Look for robust levers, cable assemblies, and mounting hardware designed to withstand truck vibrations and duty cycles.
- Aesthetics and fit: Ensure the shifter visually matches your cab interior and fits within the console cutout and shifter boot compatibility.
