Transmission fluid is a type of lubricant that is used in automatic and manual transmissions. It helps to reduce friction and wear between the gears and other moving parts of the transmission. Transmission fluid also helps to keep the transmission cool and prevents it from overheating. Checking and filling transmission fluid is an important part of maintaining your vehicle and can help to extend the life of your transmission.
There are a few different ways to check transmission fluid, but the most common method is to use the dipstick. The dipstick is usually located near the back of the engine and will have a handle with a red or orange tip. To check the transmission fluid, pull out the dipstick and wipe it clean with a rag. Then, reinsert the dipstick into the transmission and pull it out again. The fluid level should be between the two marks on the dipstick.
