Transmission fluid is a liquid that lubricates the moving parts of your transmission. Unlike gasoline, transmission fluid is not consumed through use of the vehicle, meaning the owner usually doesn't have to check it except during normal maintenance or when troubleshooting a problem with the car. If you own a 2007 Pacifica and notice harder shifting while driving the vehicle, check the transmission fluid.
Park the 2007 Pacifica on level ground, apply the parking brake and allow the engine to idle for approximately one minute.
Move the gear selector to each position for a few seconds and then place it back in park.
Locate the transmission fluid dipstick, located behind the radiator on the right side of the engine compartment, and pull it out of the fill tube. Take note of the "Hot" and "Cold" indicator marks on the end of the dipstick.
Wipe off the dipstick with a rag, reinsert it into the fill tube and pull it out again.
Check the fluid level on the dipstick in the "Hot" or "Cold" marks. Use the "Hot" mark if your engine is at regular running temperature. The 2007 Pacifica runs at normal temperature after driving it for approximately 15 miles. Use the "Cold" mark if the engine is not running at regular temperature. The fluid level should fall between the upper and lower ranges on the "Hot" or "Cold" mark. Add fluid through the fill tube if the fluid falls below the lower line.
