JEGS Shifter Solenoid With Mounting Plate
This solenoid is designed to automatically shift from low to high (1st to 2nd) while you keep both hands on the wheel. It fits Powerglide transmissions used with Hurst Quarter Stick, Quarter Stick II (rear exit cable), and B&M Pro Stick shifters. It draws only 1.22 amps at 12 volts, reducing electrical drain. Best for racers or street cars needing reliable, hands-on control without constant throttle adjustments. Limitation: compatibility is strongest with the specified shifters; verify your cable configuration before purchase.
TCI 749800 Powerglide Solenoid
The TCI 749800 is labeled as a Powerglide brake solenoid with a 0.200 in stroke. It’s positioned as a country-of-origin product from CHINA with vehicle-specific fit. Best for enthusiasts who need a straightforward brake solenoid replacement that matches common Powerglide brake configurations. Choose this if your prior solenoid used a similar brake mechanism and you require a direct fit. Limitation: may require dealer verification for exact vehicle compatibility.
JEGS 62300-1 Replacement Solenoid
Designed for Powerglide setups using Quarter Stick/II or Pro Stick shifters, this JEGS solenoid draws 1.22 amps at 12V. It’s a direct replacement option that helps restore precise shifting without altering your shifter hardware. Best for builders who need a compatible, drop-in solenoid with familiar performance. Limitation: ensure the solenoid is designed for your exact shifter model to avoid fit issues.
Coan Racing 12040 Powerglide Solenoid
Coan Racing’s 12040 is a brake solenoid sized for Powerglide transmissions, with package dimensions noted as 8.07 inches by 3.91 inches by unspecified width. Best for racers or builders using Coan components who want a matched brake solenoid option. Caution: verify overall fit with your chassis and shifter combination to prevent interference with other components.
Dorman 924-975 Shift Interlock Solenoid
Dorman’s 924-975 is a shift interlock solenoid designed as a direct-fit replacement for select models. Best for customers needing OEM-like interlock functionality replacement after wear or damage. Limitation: interlock systems vary by vehicle; confirm that this model matches your car’s interlock control scheme and wiring.
Buying Guide: Key Purchase Considerations
What is a powerglide shifter solenoid?
A powerglide shifter solenoid is an electro-mechanical device that controls shifting signals in automatic transmissions. It can drive automatic upshifts, engage or release interlocks, or control brake solenoids in Powerglide systems with various shifters. The right solenoid matches your shifter type, wiring, and the vehicle’s electrical system.
How to choose the right solenoid?
Match the solenoid to your shifter model (Quarter Stick, Pro Stick, etc.) and transmission (Powerglide). Check electrical draw (amps at 12V) to minimize battery drain. Consider whether you need a brake solenoid, interlock solenoid, or a direct replacement. Durability and mounting compatibility with your plate or bracket are important for reliability in race environments.
What about compatibility and installation?
Confirm the solenoid’s stroke, mounting footprint, and connector type align with your current setup. Some solenoids are designed for specific shifter brands (Hurst, B&M) or exit cable configurations. If in doubt, opt for a replacement solenoid designed for your exact model and cross-check with the manufacturer’s compatibility list.
Are there notable trade-offs?
Higher compatibility might come with different electrical loads or mounting requirements. In some cases, a brake solenoid is a better fit for certain transmission configurations, while an interlock solenoid suits models with safety interlocks. Always consider the overall wiring layout and space constraints inside the engine bay or dash area.
Bottom-line buying considerations
- Shifter compatibility: Ensure the solenoid works with your Hurst Quarter Stick, Quarter Stick II, or B&M Pro Stick.
- Electrical draw: Prefer lower amps to reduce cabin and engine bay drain.
- Type: Decide between brake solenoid, interlock solenoid, or direct replacement.
- Mounting: Check mounting plates, brackets, and cable exits for fitment.
- Durability: Look for robust construction for racing or daily driving.
Frequently asked questions
- Q: Do all Powerglide shifters use the same solenoid? A: No, solenoids vary by shifter type and function (brake, interlock, or direct replacement).
- Q: Is a lower amp rating always better? A: Lower amps reduce electrical drain, but ensure the solenoid still provides reliable actuation.
- Q: Can I mix solenoids from different brands? A: Compatibility depends on shifter model and transmission; verify fitment before mixing.
- Q: What maintenance is needed for a solenoid? A: Regular inspection for wiring wear, clean connectors, and ensuring mounting remains secure.
- Q: Will replacing the solenoid affect shifting feel? A: Replacing with an appropriate solenoid can restore original shifting behavior when done correctly.
- Q: Should I choose an interlock solenoid for safety interlocks? A: If your vehicle uses a safety interlock system, a dedicated interlock solenoid is recommended.
