Lubegard Highly Friction Modified Supplement, often referred to as "Dr. Tranny" Instant Shudder Fixx, is a professional-grade transmission additive designed to solve torque converter shudder and shifting issues instantly. Modern automatic transmissions rely on precise friction characteristics to operate smoothly, and over time, the fluid's ability to provide this friction degrades. Lubegard's concentrated formula restores the necessary friction profile to the transmission fluid, eliminating the annoying "shudder" that often feels like driving over rumble strips.
Torque converter shudder is a common issue that can lead to expensive transmission replacements if left unaddressed. Lubegard Highly Friction Modified provides a safe, chemical solution that revitalizes the existing ATF. It is trusted by professional transmission rebuilders and mechanics worldwide for its effectiveness and safety. This supplement does not contain harmful solvents and is engineered to enhance the performance of any ATF, ensuring smoother shifts and a quieter driving experience. It is the most effective and affordable "first step" in troubleshooting transmission vibration issues.
