The Lockup Conv Speed Control by B and M AUTOMOTIVE is a precision transmission management module designed for drivers who demand adaptive shift timing and torque converter lockup optimization. This compact control unit addresses a critical need in modern performance driving: managing the transition between fluid coupling and mechanical lock-up in automatic transmissions to maximize efficiency, reduce heat generation, and improve overall drivability. Whether you're building a street machine, tuning a truck, or refining a daily driver's performance characteristics, this speed control module gives you the ability to customize when your converter engages for optimal power delivery and fuel economy.
B and M AUTOMOTIVE engineered this controller with precision electronics to monitor vehicle speed and transmission load in real time, adjusting lockup parameters with millisecond accuracy. The compact 1.45-pound housing integrates seamlessly into existing transmission harnesses, featuring ruggedized construction rated for underhood temperatures and vibration environments typical of modified vehicles. By controlling the exact moment your torque converter transitions from slip to solid mechanical engagement, this module reduces parasitic losses, lowers transmission fluid temperatures under sustained acceleration, and eliminates the sluggish feel of early lockup engagement—delivering the responsive shift behavior that separates a well-tuned drivetrain from a stock setup.
Serious transmission builders and performance enthusiasts install the Lockup Conv Speed Control when they've optimized their torque converter and need electronic fine-tuning to match upgraded engines, altered gear ratios, or custom shift programs. This controller works across a broad range of automatic transmission platforms where aftermarket torque converter upgrades have already been installed, making it an ideal complement to high-stall converters or lock-up designs in hot rods, muscle cars, and modified trucks. Installation requires basic electrical skills and knowledge of your specific transmission's wiring architecture; consultation with your transmission specialist or builder ensures proper calibration and safe operation. For buyers seeking to maximize converter performance and transmission longevity in performance applications, the Lockup Conv Speed Control delivers measurable improvements in shift quality and thermal management.
