Automatic Transmission Wire

Advanced resistance to transmission fluid. TE's Raychem ATF wires are specifically designed for long-term performance in automatic transmission applications. The wires combine durability with excellent fluid resistance and thermally stable insulation materials.

Performance is automatic. TE's Raychem ATF wires are specifically designed for automatic transmission applications. Our automatic transmission wire has a specially-modified radiation cross-linked fluoropolymer material that provides excellent long-term performance, even when immersed in hot automatic transmission fluid. The internal gearbox wires are often immersed in hot, aggressive transmission fluid, which can rapidly degrade standard polymer insulation. The ATF wire has been approved by U.S.-based OEMs as an automatic transmission wire.
