Oil Hose Volvo 23790464

This transmission oil hose is a critical component of the transmission lubrication system for Volvo and Mack trucks, responsible for delivering transmission fluid from the transmission to the filter for contaminant removal and returning the clean fluid to the transmission, ensuring that all internal components-including gears, bearings, and friction elements-receive continuous and adequate lubrication and cooling. The product features a vulcanized rubber construction with metal fittings, offering excellent oil resistance, heat resistance, and pressure durability to maintain stable fluid delivery under high-load operating conditions. Its mounting dimensions and interfaces strictly follow Volvo original specifications for direct replacement without modification. According to Volvo official service bulletins, this part is used to replace older oil hoses on vehicles manufactured prior to November 13, 2020, with improved sealing capacity to effectively prevent fluid leakage and extend transmission service life. This component is compatible with Volvo and Mack brand trucks and serves as an essential spare part for transmission lubrication system maintenance and repair.
