Lubegard Automatic Transmission Fluid Protectant 32 oz — Lowers ATF Temp, Restores Seals

This concentrated transmission protectant is formulated to work with Dexron, Mercon and most OEM ATFs (excluding Ford Type F and CVT fluids) to help automatic and manual transmissions run cooler, resist oxidation, and maintain shift quality. Using Lubegard's LXE (Liquid Wax Ester) technology, the product increases an ATF's thermal and oxidative stability so fluid properties remain consistent under higher temperatures and prolonged stress. It is compatible with both synthetic and conventional fluids and is safe when used at recommended dosages.

How does Lubegard 50902 lower transmission temperatures?

The formulation improves the fluid's ability to transfer heat away from clutch packs and bearings, which reduces peak operating temperatures. Lower temperatures slow thermal breakdown and limit the formation of varnish and sludge. Quieter, more consistent operation is a common outcome when heat-related wear is reduced.

• Reduces elevated operating temperatures by up to 40°F in many applications
• Enhances fluid heat-transfer properties for more efficient cooling
• Helps prevent thermal thinning and pyrolization of ATF

Will this additive affect shifting or cause clutch slippage?

Lubegard 50902 is designed to preserve friction characteristics of automatic transmission fluids, so it does not create clutch slip or upset shift feel when used as directed. In many cases it smooths harsh or abrupt shifts and eliminates torque converter shudder. Proper dosing is important—overfilling or excessive concentrate can alter performance.

• Formulated to avoid clutch friction upset
• Softens and refines harsh shifts for quicker, smoother transitions
• Reduces torque converter shudder and eliminates clutch chatter

How does it protect seals and extend fluid life?

The LXE components condition rubber and polymer seals, helping to restore older seals and protect new ones without causing swelling or deterioration. By increasing oxidative stability, the additive slows fluid aging so ATF retains viscosity and protective qualities longer. That translates into extended fluid life and fewer premature service intervals.

• Conditions and can restore aged seals to near-new performance
• Raises oxidative and thermal stability to slow fluid breakdown
• Limits foaming and oxidation that accelerate wear and deposits

How should I use Lubegard 50902 in my vehicle?

Add Lubegard to the transmission while the engine is idling and the vehicle is in park. Use 1 ounce (29.6 mL) per quart (liter) of total transmission capacity, including the torque converter. Do not use in Ford Type F or CVT systems and avoid overfilling; always verify compatibility with your vehicle's ATF type first.

• Dosage: 1 oz per quart (liter) of ATF capacity (include torque converter)
• Add with engine idling and transmission in park, then check level—do not overfill
• Suitable for Allison and other heavy-duty ATF applications except Type F and CVT

Who is this for: Lubegard 50902 is aimed at technicians, fleet managers, and DIY vehicle owners who need to control transmission temperatures, reduce wear, and preserve or restore seal performance in automatic and compatible manual transmissions. It suits cars, light trucks, and heavy-duty units using Dexron, Mercon, or OEM ATF formulations (excluding Ford Type F and CVT). If you routinely tow, run in hot climates, or want to extend transmission fluid life and improve shift quality, this protectant is a practical addition to scheduled maintenance.
