This product is a fluid additive and leak repair treatment compatible with most automatic transmissions (not for CVT or manual gearboxes). It is intended to be used as part of routine service or to delay more invasive repairs by conditioning seals and restoring internal leakage control.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Trans-X stop transmission leaks?\u003c\/h3\u003e\n\u003cp\u003eTrans-X uses a blend of conditioners and seal-swelling agents that interact with aged rubber and polymer seals to reduce seepage. It does not weld or permanently bond metal parts, but it helps swell and soften worn seals so they better conform and limit fluid loss.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFormulated to penetrate and condition hardened seals and gaskets.\u003c\/li\u003e\n  \u003cli\u003eReduces small external seepage that develops with age and mileage.\u003c\/li\u003e\n  \u003cli\u003eCompatible with most automatic transmission fluids when used per directions.\u003c\/li\u003e\n  \u003cli\u003eMeant as a maintenance step, not a chassis rebuild substitute.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill Trans-X fix slipping and rough shifting?\u003c\/h3\u003e\n\u003cp\u003eTrans-X can improve shifting feel in many high-mileage automatics by restoring proper pressure and seal integrity, which helps minimize internal fluid loss that causes slipping.
