How to check if your transmission fluid is low

Take the dipstick out, wipe it down with a clean rag or paper towel, then put it back into the transmission fill tube. Pull the dipstick back out of the tube, and check the fluid level against the markings near the end of the dipstick. Fluid can be added if necessary.

Not being able to shift is a direct result of having low transmission fluid. Slipping Gears - On the flipside, slipping out of gear is another side effect of having low transmission fluid. For example, you may be maintaining your current speed, then suddenly feel your vehicle downshift or shift to a higher gear.
