• Reduces operating temperatures
• Eliminates station from all automatic & CVT transmissions
• Reduces coefficient of friction
• Transmission station eliminator minimizes metal to metal contact
• Eliminates rust & corrosion

Hot Shot's Secret

• Bar’s Leaks CVT Transmission Fix is a synthetic blend treatment for the transmission fluid, seals and metal surfaces, your vehicle is a good candidate for this solution if you are noticing excessive noise, shudder, slipping, leaks, or low overall performance in your CVT
• CVT (Continuously Variable Transmission) design is fundamentally different from a traditional automatic transmission, conventional ATF (Automatic Transmission Fluid) and additives cannot be used in these specialized transmissions.
• Extreme Pressure/Anti Wear Agents
• Seal Conditioner and Cleaning Detergents
• Performance additive booster

Bar's Leaks

• Prevents overheating, reducing elevated operating temperatures up to 40 degrees Farenheit - Optimizes total transmission performance
• Eliminates transmission fluid foaming and oxidation and reduces wear throughout the transmission
• Eliminates clutch chatter and torque converter shudder; Softens and modifies harsh shifts making them quicker in duration
• Extends fluid life / Raises the thermal and oxidative stability of the fluid
• Only protectant that increases the fluid’s ability to transfer heat / Protects new seals and permanently restores older seals to a like-new condition, without adverse side effects
