4T40-E Automatic Transaxle

Oil Pan, Gasket & Filter:






Checking oil level, color and condition at regular intervals will provide early diagnosis information about the transaxle. This information may then be used to correct a condition that, if not detected early, could result in major transaxle repairs.

When adding or changing oil, use only DEXRON III.

Important
When new, automatic transmission oil is red in color. The red dye is to distinguish it from engine oil or anti-freeze. The red dye is not an indicator of oil quality and is not permanent. As the vehicle is driven the transmission oil will begin to look darker in color. The color may eventually appear light brown. A dark brown color with a burnt odor may indicate oil deterioration and signal a need for a transaxle oil change.

NOTICE: Do not overfill. Overfilling will cause foaming, loss of oil and possible damage to the transaxle.
