CVO 1/27/2013Learning how to check transmission fluid is very simple and can keep your transmission fluid levels from reaching dangerously low levels. There are only a few steps in checking your transmission fluid level. First you need to make sure that your vehicle is parked on a level surface. When checking your transmission fluid level, some vehicles must be running. Check your owner's manual to verify whether or not the vehicle should be running or not during transmission fluid check. With the engine warm, locate the transmission fluid dipstick. Most, if not all, are located at the back of the vehicle's engine. Remove the dipstick and clean it off with a clean rag. Make sure the transmission dipstick is absolutely clean when inserting it back into the transmission. Foreign objects in the fluid, even miniscule ones, can severely shorten the life of your transmission. Now, fully replace the dipstick back into the dipstick tube and then pull it out again. There may be two readings, hot (warm) and cold. You will be reading the hot (warm) level reading. Fluid level should indicate Full on the dipstick. If is low, add the correct transmission fluid until you see the level indicate Full. You add transmission fluid through the transmission dipstick tube. It is best to buy a long suitable funnel made for just this purpose. It is very important not to add too much transmission fluid when filling. Once your dipstick is indicating a Full transmission fluid level, you can replace the dipstick.
