How do you properly check transmission fluid?

Check the fluid. Dip the tip of your index finger into the fluid on the dipstick and rub the fluid between your finger and the tip of your thumb. The transmission fluid on the dipstick should be pinkish and almost clear. If it looks or smells burnt or has particles in it, have a mechanic drain and change the fluid.

Regarding this, do you check your transmission fluid when it's hot or cold?

Transmission fluid is checked when it's hot (up to running temperature). As the fluid gets up to temperature it expands. If the fluid is cold, it won't give the proper level reading, thus overfilling will ensue. One of the main fluid compartments of the transmission is the torque converter.

Secondly, how do you read the transmission fluid on a hot dipstick? Pull the dipstick out again and check the fluid level. If the engine is cool, it should be at the upper end of the “COLD” mark. If the engine is hot, the level should be at the upper end of the “HOT” mark. If it's lower, you should add some amount of automatic transmission fluid.
