Description

The B and M AUTOMOTIVE Converter Lockup Control (Part #70248) is a precision electronic module specifically designed for managing torque converter engagement in GM automatic transmissions, such as the 700R4, 4L60E, and 4L80E. This product is ideal for automotive enthusiasts looking to enhance performance in street machines, drag racing platforms, or daily drivers.

The module allows users to fine-tune converter lockup timing, optimizing both drivability and fuel economy. It works by intercepting factory solenoid signals and applying real-time logic to maintain lockup across a broader RPM range, thus improving power delivery and reducing heat generation. The compact design facilitates easy installation in engine bay or under-dash locations without the need for transmission pan removal.

Transmission builders and performance shops will find this control unit essential for enhancing transmission responsiveness and longevity. By reducing friction and thermal stress, it significantly improves shift quality and overall drivability. This product is specifically tailored for GM automatic transmissions, ensuring compatibility and optimal performance.
