BG ATC Plus automatic transmission additive — 1 pint, seal conditioner & deposit remover

BG ATC Plus is an advanced transmission additive designed to prevent deposit buildup, condition seals, and extend the life of automatic transmission fluid in modern multi‑speed gearboxes.

Modern vehicles with 8-, 9- and 10-speed automatic transmissions push fluid chemistry harder than ever. Higher operating temperatures and tighter tolerances accelerate fluid breakdown, leading to varnish, sludge, erratic shifting and premature wear. BG ATC Plus is formulated to boost both new and in-service automatic transmission fluids so they resist oxidation, reduce foaming and help keep internal components clean and seals pliable.

How does BG ATC Plus protect transmissions in high‑gear, high‑temperature environments?

BG ATC Plus uses updated additive chemistry to improve oxidation stability and reduce the rate of fluid degradation under sustained heat. By limiting fluid breakdown it lowers the chance of deposit formation on valves, clutches and other critical parts.

• Enhances fluid thermal and oxidative resistance
• Reduces formation of sludge, varnish and deposits
• Minimizes foaming for consistent hydraulic performance
• Helps maintain smooth hydraulic control in tight‑tolerance transmissions

Can it correct existing shifting problems like shudder or erratic shifts?

When used as part of a professional BG transmission service and paired with BG Universal Synthetic ATF, BG ATC Plus helps dissolve and prevent deposits that contribute to shudder and rough shifting. It conditions internal surfaces so shift timing and feel are restored.

• Helps remove varnish and clutch deposits that cause shudder
• Improves clutch friction characteristics for steadier shifts
• Works with synthetic ATF to recondition worn fluid systems

Will BG ATC Plus help with leaks and softening seals?

BG ATC Plus contains seal conditioners that restore flexibility to hardened elastomers, which can reduce leak paths without harming seal materials. It’s formulated to be compatible with typical automatic transmission fluid seal compounds.

• Softens and conditions seals to reduce leaks
• Compatible with common ATF seal materials when used per directions
• Helps maintain proper pressure and reduce fluid loss

How do I use this product in routine transmission maintenance?

BG ATC Plus is intended for professional service applications and is most effective when added during a transmission fluid change or BG Transmission Service. Follow product dosing guidance and pair with a high‑quality synthetic ATF for best results.

• Installed during ATF replacement or system service
• Works best when combined with BG Universal Synthetic ATF
• Part of a preventive maintenance program to extend transmission life

Who is this for: BG ATC Plus is aimed at professional technicians and vehicle owners who demand extended transmission life and reliable shifting from modern multi‑speed automatic gearboxes. It’s particularly useful for vehicles that tow, carry heavy loads or operate in hot climates where transmission fluid is exposed to high stress. Note: follow safety guidance and local regulations when handling chemical products; this product may contain substances listed by some jurisdictions as hazardous.
