How to Check Transmission Fluid?
2 Answers
Transmission fluid inspection method: 1. Park the vehicle on a level surface; 2. Start the engine and warm it up until the coolant temperature reaches above 90 degrees Celsius, keeping the engine running; 3. Depress the brake pedal and shift the gear lever from P position through each gear before returning to P position, allowing the fluid to enter the valve body and corresponding oil passages; 4. Remove the dipstick to check the fluid level, ensuring it's between the upper and lower marks on the dipstick. Proper automatic transmission fluid level inspection must be performed with the engine warmed up. The vehicle engine must not be turned off when checking the HOT range. The COLD mark is for reference only and should not be used to determine transmission fluid level.
I've been driving for over twenty years, and checking transmission oil starts with warming up the car. Start the engine and let it run for five to ten minutes to bring the oil temperature to normal levels. Then park on level ground, turn off the engine, locate the transmission dipstick in the engine bay, pull it out, wipe it clean, reinsert it all the way, wait a few seconds, and pull it out again to check the oil level. The oil mark should be between the high and low indicators; if it's too low, add the same type of oil, but don't overfill. Also, pay attention to the oil's color and smell: fresh oil is bright red, but if it turns black or has a burnt odor, it's time for a change. Neglecting this check can lead to transmission wear, even gear-shifting issues, and costly repairs. I check mine every quarter or every 5,000 kilometers, and I always recommend keeping some spare oil in the car for emergencies. Developing this habit helps avoid major problems, saving money and giving peace of mind.
