GM Torque Converter Lock-Up System

Experience enhanced performance and smooth gear transitions with Ron Francis' Wiring GM Torque Converter Lock-Up for 200R4, 350 Turbo, and early 700R4 transmissions. This advanced system is designed to lock up the converter at a set speed, optimizing the engine's efficiency and providing a seamless driving experience. With its electronic control, this unit offers unparalleled performance without relying on the factory computer (ECM), making it a perfect upgrade for any enthusiast looking to elevate their vehicle's driving dynamics.

Technical Specifications

This high-quality system is not vacuum controlled, ensuring reliability and precision. It utilizes a sensor that reads the vehicle's speed through the speedometer cable, making it compatible with transmissions featuring factory internal speed generators. For those with early models, a conversion to cable drive is necessary for optimal performance. The system is pre-set to lock up the converter at 42-47 MPH, but it is fully adjustable to meet your specific needs. Key features include:

  • Electronic Control - No need for vacuum lines, offering a clean and efficient setup.
  • Speed Sensor Integration - Utilizes the speedometer cable for accurate speed readings.
  • Adjustable Lock-Up Speed - Tailor the system to your driving preferences and performance requirements.

Practical Benefits and Target Audience

The Ron Francis Wiring GM Torque Converter Lock-Up is an essential upgrade for drivers seeking improved acceleration and efficiency. Whether you're a car enthusiast, a weekend warrior, or a daily driver, this system offers numerous benefits:

  • Enhanced Performance - The lock-up feature reduces slippage, providing smoother gear shifts and increased acceleration.
  • Improved Fuel Efficiency - Locking up the converter at a set speed optimizes engine efficiency, leading to better fuel economy.
This product is ideal for those who want to extract the maximum potential from their 200R4, 350 Turbo, or early 700R4 transmissions, delivering a driving experience that is both exhilarating and practical.
