How to Check Automatic Transmission Fluid?
2 Answers
Methods for checking automatic transmission fluid: 1. For transmissions equipped with a dipstick, check the fluid level using the dipstick markings - generally, the level should not exceed the maximum mark nor fall below the minimum mark; 2. For transmissions without a dipstick, there is typically an inspection screw on the side of the transmission housing. Remove this screw - if transmission fluid flows out, the level is normal. Different transmission types require different inspection methods, such as dipstick measurement, overflow tube inspection, or inspection port checking. Therefore, it's necessary to know the transmission model or vehicle VIN to consult relevant technical data. Transmission (commonly called gearbox in automotive applications or speed variator in industrial machinery) is a mechanical or hydraulic device for mechanical power conversion.
I prefer to check the transmission fluid myself, as regular inspections can prevent transmission failures. The operation should be performed with the engine idling or just after turning it off, and the car must be parked on level ground. First, locate the transmission dipstick under the hood, pull it out, wipe it clean, then reinsert it fully and pull it out again to check the fluid level. The fluid level should be between the high and low marks; if it's too low, there might be a leak, and if it's too high, it can foam and affect lubrication. The quality of the fluid is also crucial: a clean, transparent red color is ideal, but if it turns dark brown or has a burnt smell, it's time for a change. I recommend checking it every six months, combined with the guidance from the owner's manual, to extend the transmission's lifespan. Never reach in directly when the engine is hot to avoid burns.
