This manual transmission fluid pump is designed for clean, controlled fluid transfer for automotive and marine maintenance. Its 3 L HDPE reservoir offers durability and easy fluid level monitoring during use. The hand-operated piston press design requires no power or air line, making it convenient for garages, driveways, and mobile service jobs. A flexible hose setup helps reach tight spaces, while the leak-secure design supports tidier operation. It is suitable for transferring engine oil, coolant, brake fluid, and transmission fluid.
