No, Valvoline 855459 Transfer Case Fluid should not be used as a transmission fluid. While transfer case fluid and transmission fluid may have similar properties, they are formulated for different purposes and are designed to meet different specifications set by vehicle manufacturers.
Key Differences Between Transfer Case Fluid and Transmission Fluid:-
Specific Formulation and Purpose:
- Transfer Case Fluid (such as Valvoline 855459) is specifically formulated to lubricate and protect the gears, chains, bearings, and other components inside a transfer case. It is designed to handle the specific requirements of transfer cases, which often include high torque loads, differentials, and engagement mechanisms for 4WD and AWD systems.
- Transmission Fluid is formulated to provide lubrication, cooling, and hydraulic pressure for automatic transmissions, which have a different set of requirements. Transmission fluids are often designed to handle clutch engagements, friction between moving parts, and the hydraulic circuits that control gear shifts.
-
Different Additive Packages:
- Transmission Fluids contain specific additives to manage heat, provide the right friction characteristics for clutches and bands, and handle oxidation stability at high temperatures.
- Transfer Case Fluids like Valvoline 855459 are designed to prevent wear, reduce friction between metal surfaces, and provide protection against rust and corrosion. These fluids may lack the friction modifiers and additives required for optimal transmission performance.
-
Compatibility and Specifications:
- Transmission Fluid Requirements: Automatic transmissions require specific types of fluids, such as DEXRON®, MERCON®, ATF+4®, or other manufacturer-specific types. These fluids have precise frictional properties and viscosity characteristics essential for the proper function of the transmission.
- Transfer Case Fluid Requirements: Transfer cases, on the other hand, may require different types of fluids based on the manufacturer and design. Even though some transfer cases use ATF (Automatic Transmission Fluid) types, the transfer case fluid is still different in terms of the formulation specifics and requirements.
- Potential Damage: Using a transfer case fluid as a transmission fluid could lead to improper lubrication and inadequate cooling in the transmission. This could cause overheating, increased wear, slipping, and eventual failure of transmission components.
- Incorrect Friction Characteristics: The lack of appropriate friction modifiers could lead to erratic gear shifts, clutch slippage, or even complete failure of the transmission.
- Warranty and Reliability Concerns: Using the wrong type of fluid could void your vehicle’s warranty and lead to expensive repairs.
- Valvoline 855459 should only be used in transfer cases that require a fluid compatible with its specifications. It is suitable for many transfer cases that call for a synthetic, high-performance fluid and is designed to meet or exceed several OEM requirements for transfer case lubricants.
You should not use Valvoline 855459 Transfer Case Fluid as a transmission fluid. Instead, use the specific type of transmission fluid recommended by your vehicle’s manufacturer, as listed in the owner’s manual. Always use the correct fluid type for both your transfer case and transmission to ensure proper operation and longevity of your vehicle’s drivetrain components.
