Sunsong is a vertically integrated maker of automotive fluid transfer hoses and lines. It designs this assembly to deliver exact form, fit, and function.
- Pre-bent to fit: The hose is precision-engineered with pre-bent tubing. Brackets, grommets, heat shields, bushings, and protective sleeves are included where the application requires them, so the wearable parts are returned to original condition.
- Zinc-plated steel tubing: The steel tubing is electroplated with a zinc coating for corrosion and rust resistance against high humidity, road salt, water, and grime.
- Wide temperature range: It is rated for -40 to 350°F, which goes beyond original-equipment requirements.
- Performance standard: It is built to match or surpass original-equipment performance standards.
Specifications: Both ends have quick-connect fittings. Overall length is 41 in (1042 mm). The cataloged position is inlet to transmission (passenger side), outlet (passenger side) to transmission (rear). The listed applications use one per vehicle. Country of origin: Thailand.
Signs this hose may need replacing include transmission fluid leaking at the lines or fittings, a falling fluid level, and rusted, kinked, or damaged tubing.
