The ultimate racing transmission oil for Honda CR, CRD and TRX models.
Ultra-high film strength and shear stability reduces transmission wear.
High thermal stability prevents foaming and premature oil breakdown.
Anti-friction additives allow smoother shifting, while minimizing drag and power loss.
Anti-shear additives increase clutch life reduce clutch slippage.

Seal Conditioner – stops current and prevents future leaks by protecting and reconditioning seals..
Extreme Pressure (EP) and Anti-Wear (AW) Agents – provide excellent metal-to-metal wear protection reducing noise and gear temperatures. Our sulfur, nitrogen and phosphorus additives meet the requirements of API GL-4 and GL-5 specifications..
Friction Modifier – supplements the EP/AW additives to help reduce noise and wear. This in turn helps shifting in a manual transmission and also stops chatter in limited-slip posi-traction axles..
Performance Additive Booster – includes tackifying agents and highly sheer-stable multigrade viscosity modifiers to keep oil on the gears and bearings where it can better lubricate, especially at higher temperatures. Pour Point Depressant (PPD) allows product to flow even at very low temps..
Manufactured in the USA, this product works in all manual gearboxes, differentials, open & posi axles and more. Stops pinion, axle, output shaft and other seal leaks. Reduces grinding, whining, clunking and protects gears..

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..
Seal Conditioner and Cleaning Detergents.

The automatic transmission box is constantly subjected to various overload environments, to ensure its efficiency and durability you should apply additives for the transmission. The additives provide protection to the gearbox, avoiding the wear and tear of the gears, benefiting in a smoother and noiseless operation..

High-performance high-pressure transmission oil made from high-grade synthetic base oils and additives..
For the most extremely stressed motorcycle transmission and final drives..
Comply with the transmission manufacturers instructions..

Specially designed to withstand the harsh detergents and additives found in automatic transmission ﬂuid.
Formulated to resist aging, weathering and thermal cycling without hardening, shrinking or cracking.
Improves transmission oil resistance and provides good adhesion while retaining flexibility.
Sensor-safe, non-corrosive, non-flammable, non-toxic, and low odor sealant can be used as a gasket maker or dressing.
Suggested Applications: Automatic transmission pans, case halves and inside covers.
