Lubegard Dr. Tranny Automatic Transmission Shudder Fix 6-Pack — 6 x 2 oz concentrated friction modifier, works with conventional &

Dr. Tranny Lubegard Automatic Transmission Instant Shudder FIX is a concentrated friction modifier designed to instantly stop torque‑converter lock‑up shudder when added to automatic transmission fluid.

This six‑pack contains six 2‑ounce application tubes of the original Dr. Tranny formula from Lubegard. Each concentrated dose is engineered to work with conventional and synthetic ATF to reduce clutch chatter and improve drivability without replacing fluid. The product is compatible with most automatic transmissions but is not intended for Ford Type F or CVT systems; for ongoing protection, consider pairing it with Lubegard ATF Protectant (P/N 60902 / M465L).

How quickly will I notice reduced shudder after treating my transmission?

Most users observe a reduction in torque‑converter shudder shortly after application—often within minutes of driving as the product mixes with the ATF. Results depend on the severity of the condition and how well the tube’s contents disperse through the fluid circuit.

• Single 2 oz dose per treatment; use one tube per application as directed.
• Mixes with either conventional or synthetic ATF.
• Effective almost immediately in many vehicles once fluid temperature and circulation allow mixing.

Will this work with my transmission fluid and reduce wear?

Dr. Tranny is a concentrated friction modifier compatible with most automatic transmission fluids and formulated to lower friction-related wear. It claims to provide up to four times less wear compared to untreated ATF when used as directed, helping clutch surfaces operate more smoothly.

• Compatible with most ATF types, excluding Ford Type F and CVT fluids.
• Concentrated synthetic ester chemistry for targeted friction control.
• Designed to complement regular ATF maintenance, not replace full service when needed.

How is the product packaged and applied?

Each six‑pack includes individually engineered two‑ounce applicator tubes for precise dosing and easy addition through the transmission dipstick or fill port. The small tube design makes it simple to introduce the modifier into the fluid without spills or mess.

• Six 2 oz tubes per pack for multiple treatments or multiple vehicles.
• Application via dipstick/fill port—follow manufacturer and product instructions.
• Concentrated formulation—one tube treats a typical automatic transmission fluid volume.

Are there any fluids or vehicles where I should not use this?

Do not use Dr. Tranny in Ford Type F transmissions or any continuously variable transmissions (CVTs). Always check your vehicle service manual and compatibility notes before adding any additive to the transmission system.

• Not recommended for Ford Type F ATF applications.
• Not for CVT gearboxes; CVTs require fluid and additives specific to their design.
• If in doubt, consult a transmission professional or Lubegard technical guidance.

Who is this for? If you own a vehicle with an automatic transmission showing torque‑converter lock‑up shudder, clutch chatter, or judder and you want a concentrated, professional‑grade fix without an immediate fluid change, this Lubegard Dr. Tranny 6‑pack provides multiple, easy doses. It’s intended for do‑it‑yourselfers and professional technicians who need a targeted friction modifier compatible with most ATFs (excluding Ford Type F and CVTs). For ongoing transmission longevity and additional protection, combine periodic use with recommended ATF maintenance and consider Lubegard’s ATF Protectant for longer‑term benefits.
