Durable stainless steel construction Made from high-end stainless steel for long-lasting use and superior rust resistance compared with ordinary iron or aluminum dipsticks. Maintains accuracy and appearance after repeated use in harsh under-hood conditions. Accurate, reliable fluid level checks Built-in O-ring seals the top of the dipstick to help prevent air or fluid bypass, enabling more reliable readings. Insert the dipstick into the transmission fill tube until it bottoms out, then pull out and read the level on the rod. For the most accurate result, wipe the dipstick clean after the first pull, reinsert, and read the fluid level on the second pull. Easy-to-read markings and clear safety indicator The rod features clear, high-contrast marks and a visible slogan to make oil level reading straightforward. A prominent "Safe" mark shows the correct operating range at a glance, reducing guesswork and the risk of overfill or underfill. Function and compatibility Designed specifically as a transmission oil dipstick for vehicles that use a dipstick-style transmission fill tube. Simple to use during routine maintenance, fluid changes, or post-repair checks; does not alter vehicle systems. Practical use scenarios Pre-trip inspection: Quickly verify transmission fluid level before a long drive to reduce risk of transmission issues on the road. After service or fluid change: Confirm correct fill level immediately after topping or replacing transmission fluid. Troubleshooting: Use during routine diagnostics to check for low fluid or contamination indicators. Why this dipstick matters Durable material reduces corrosion and wear, so you get consistent readings over time. The O-ring and clear markings make readings more dependable than basic metal or stamped alternatives. Easy cleaning and re-insertion procedure ensures accuracy without special tools.
