Product Description

Details

This is a 2 quart bottle - Recommended a total of 6 quarts (3 bottles) to fill a G56 Transmission

WHY WE RECOMMEND SCHAEFFER’S 239S SAE 50 AS A FLUID REPLACEMENT FOR G56 TRANSMISSIONS

Getrag, a subsidiary of Mercedes Benz, manufactures the G56 transmissions that are in 5.9L and 6.7L Dodge turbo diesels newer than 2006. Chrysler's factory setup of the transmission utilizes a dual mass flywheel with a single disk clutch and it is filled with ATF+4 automatic transmission fluid.

While this setup may work in its stock configuration, it often creates a problem when G56 drivers upgrade their clutch. Most aftermarket clutches use a solid flywheel for performance and durability, but solid flywheels don’t absorb harmonics as well as dual mass flywheels. In high torque conditions, this creates a gear roll over which results in a growling noise coming from the transmission. This growling noise is most apparent in 4th and 5th gear at low RPMs under load.

When trying to get to the bottom of this, the folks over at CarboniteCummins found that, in fact, Mercedes Benz never intended the G56 transmission to be filled with the ATF+4 fluid. Chrysler decided on this oil not because it was the best choice, but because it was the most available at their dealerships and is 'good enough' for stock engine power setups. It saved Chrysler a lot of money, but it's not a good solution for anyone with a G56 transmission that plans on upgrading their truck. For this reason, we recommend the better-suited Schaeffer's Oil SAE 50 gear oil.

239S SUPER LUBE SUPREME SAE 50

Super Lube Supreme is a premium high performance para-synthetic fluid that is specially formulated to meet the demanding requirements of modern transmission, final drive, oil immersed brake and hydraulic systems of heavy duty vehicles.

Today’s drive-trains are more complex in design and are using more advanced high-tech materials to improve power transfer and performance in terms of load, speed, control, precision and reliability. As a result of these complex designs, the equipment requires the use of fluids that are formulated specifically to optimize friction control performance, wear protection, materials compatibility thermal and oxidation stability, shear stability, protection against foaming and rust and corrosion protection. Because of these aspects the lubricants that are used in this application must be specially formulated to meet and exceed these requirements in order to provide balanced clutch-friction retention and slippage control, compatibility with clutch materials and elastomers, increased levels of anti-wear and load carrying capability to reduce gear, bearing and pump wear, oxidative stability to prevent the formation of sludge and deposit formation, shear stability to maintain viscosity grade and film thickness protection and protection against foaming.

SCHAEFFER’S SYNTHETIC-BASED FLUIDS

Super Lube Supreme is blended from the finest severely hydro-treated polyalphaolefin synthetic base fluids and severely solvent refined, severely hydrofinished 100% pure paraffin base oils available. This unique combination provides Super Lube Supreme with superior oxidation, excellent film strength, excellent thermal and oxidation stability, excellent resistance to thermal degradation and lower volatility characteristics.

Blended into these para-synthetic base fluids is a very specialized non-corrosive high performance additive system that provides excellent wear protection and material compatibility while maximizing equipment life. This specialized high tech additive package allows the Super Lube Supreme to provide the following performance benefits:

  1. Balanced and controlled static and dynamic friction performance to provide optimized clutch friction retention and slippage control. This results in the elimination of problems with excessive brake noise and weakening of friction binders thereby assisting in longer trouble free equipment life.
  2. Excellent oxidative and thermal stability in order to prevent and eliminate the formation of sludge and varnish that can damage seals and elastomeric clutch materials.
  3. Excellent wear protection for gears, bearings and friction materials.
  4. Excellent stay-in-grade performance and shear stability in order to provide long term anti-wear protection and sustained applied pressure. Super Lube Supreme does not contain viscosity index improvers.
  5. Superior protection against copper corrosion and rusting of ferrous metal parts.
  6. Very good low temperature fluidity in order to provide easier cold weather starting and better wear protection under low temperature operating conditions.

BENEFITS OF MICRON MOLY

Further blended into the para-synthetic base oils and the highly specialized additive package is Micron Moly®. Micron Moly® is a liquid soluble type of moly that plated itself to the metal surfaces of the various components, thus forming a solid lubricant film that is able to withstand pressures up to 500,000 lbs. per square inch. This translates into better wear protection for the metallic components of the power-shift transmission and for the hydraulic system, thus extending operating life and providing an extra margin of safety for service.
