Lubegard Platinum Automatic Transmission Fluid Protectant 10 oz — reduces shudder, restores friction modifiers

Lubegard 63010 Platinum Automatic Transmission Fluid Protectant is a 10 oz additive that converts many conventional Dexron/Mercon ATFs to OEM-equivalent, friction‑modified ATF performance while reducing shudder, slip and noise.

Designed for professional technicians and DIYers who want dealer-like transmission behavior without stocking multiple factory fluids, this 10 oz bottle of Lubegard Platinum ATF Protectant uses proprietary LXE technology to condition fluid, restore depleted additives and improve shift feel. It’s formulated to match the friction characteristics of many manufacturer‑specific ATFs (for example certain Honda, Toyota and Mopar specs) and to protect internal components from heat and wear. Use it to convert compatible ATFs to higher-performance types or as a supplementary protectant in OE fluids — following the conversion chart and proper fill procedures is essential.

How does this product improve shifting and stop transmission shudder?

Lubegard Platinum contains patented Synergol TMS and LXE technology that adjusts friction properties inside the fluid film, tightening shift events and smoothing torque‑converter lockup without changing fluid sulfur balance. Those molecular modifiers reduce the micro-slip that causes shudder and can restore crisp, consistent shifts in transmissions with depleted additive packages.

• Tightens shift timing for firmer, cleaner shifts
• Reduces torque‑converter shudder at lockup
• Restores friction modifiers lost from older or diluted ATF
• Compatible with many Dexron/Mercon ATFs when following the conversion chart

Will this harm my transmission or change the original fluid chemistry?

When used as directed, Lubegard Platinum is non‑corrosive to yellow metals and does not introduce ash-producing zinc compounds; it’s formulated to avoid upsetting sulfur balance critical to certain valve body calibrations. It’s not recommended for Ford Type F fluids or CVT transmissions, so verify compatibility for your vehicle before adding.

• Does not contain ZDDP/ash that can upset modern formulations
• Safe for yellow metals and factory seals when used per instructions
• Not for use with Ford Type F ATF or continuously variable transmissions (CVTs)
• Follow the Lubegard ATF Conversion & Refill Chart for correct dosing

How much should I add and how is it applied?

Use 1 ounce of Lubegard Platinum per quart (liter) of transmission capacity for normal applications, adding it with the engine idling in Park and ensuring you do not overfill. For conversion applications — shifting a Dexron/Mercon baseline to a dealer‑type ATF performance — always consult Lubegard’s conversion and refill chart to confirm quantities and compatibility before treatment.

• Standard dosing: 1 oz per quart (29.6 mL per L) of total transmission capacity
• Add with engine idling in Park; check fluid level, avoid overfill
• Use the manufacturer chart for conversion guidance and specific vehicle listings
• Professional technicians commonly use it during repairs and refills

What protection and longevity benefits can I expect?

Beyond immediate drivability improvements, Lubegard Platinum helps inhibit oxidation and foaming, conditions seals and can extend fluid life when used appropriately. It reduces wear on internal components and stabilizes the transmission environment against heat and mechanical stress, supporting longer service intervals compared with untreated fluid.

• Inhibits fluid oxidation and reduces foaming
• Conditions and helps restore seals and O‑rings to prevent leaks
• Reduces wear on clutch packs, bands and valve bodies
• Can extend fluid change intervals when combined with proper maintenance

Who is this for? Lubegard 63010 Platinum ATF Protectant is ideal for transmission shops, fleet maintenance teams and informed vehicle owners who need a reliable conversion or top‑up solution to achieve dealer‑equivalent shift feel without carrying numerous OEM fluids. It’s suited for vehicles where Dexron/Mercon baseline ATF can be converted to higher friction‑modified types — but not for CVTs or Ford Type F systems. Always consult Lubegard’s conversion chart and your vehicle manual before use.
