Ron Francis Wiring GM Torque Converter Lock-up

The Ron Francis Wiring GM Torque Converter Lock-up is a high-quality system designed specifically for 4L60 transmissions with a round 5 pin connector. This innovative unit offers a seamless and efficient locking mechanism for your torque converter, enhancing your vehicle's performance and fuel efficiency. With its electronic control, this system operates independently of the factory ECM, providing a reliable and hassle-free experience.

Key Features and Specifications

This Torque Converter Lock-up is designed to lock up the converter at a set speed, typically between 42-47 MPH, and unlock it when the vehicle speed drops below the lock-up speed or when the brakes are applied. The system utilizes a sensor that attaches to the speedometer cable to read the vehicle's speed, ensuring accurate and responsive locking. For transmissions with factory internal speed generators, a conversion to cable drive is required to use this unit. Not compatible with 4L60E transmissions, this lock-up is a perfect fit for those seeking improved performance and efficiency in their GM vehicles.

Practical Uses and Benefits

The Ron Francis Wiring GM Torque Converter Lock-up is an ideal solution for drivers looking to enhance their vehicle's performance and fuel economy. By locking up the converter at a set speed, this system reduces engine drag and improves overall efficiency, resulting in better acceleration and lower fuel consumption. Whether you're a daily driver or a performance enthusiast, this lock-up is designed to provide you with a smoother and more responsive driving experience. With its easy installation and user-friendly adjustments, this product is suitable for a wide range of users, from DIY enthusiasts to professional mechanics.
