Red Line 50305 MT-90 75W-90 GL-4 Manual Transmission and Transaxle Lubricant (MTL) - 1 Gallon

This transmission lubricant helps keep manual transmissions and transaxles working smoothly. It protects moving parts so they can shift properly and last longer during everyday driving. The oil flows well when the transmission is cold and stays strong when it gets hot. This helps gears work smoothly in different driving conditions and supports consistent performance. The formula is designed to reduce wear and help keep parts clean inside the transmission. It supports smooth gear changes and reliable operation over time. The 1-gallon size is ideal for full fluid changes or servicing multiple vehicles and is easy to store in a garage or workshop.
