Welcome to 2carpros
The first thing to check is the fluid level. For an automatic transmission to function normally, the fluid level must be between the "full" and "add" marks on the dipstick. If the fluid level is low, the transmission may slip or engage slowly(specially in morning when everything is cold). If the level is too high, the fluid can become mixed with air (aerated) causing shifting problems, slippage and noise.
Check the level when the transmission is hot. On most vehicles this is done with the engine idling and the transmission in Park. Moving the gear selector thorough each gear position prior to checking the level will help assure an accurate reading.
Under normal driving conditions, a transmission should not use any fluid. A low level, therefore, usually indicates a leak. A visual inspection of the pan gasket and driveshaft seals will tell you where the fluid is going.
Next, check for fluid oxidation. The sniff test is a good one, but a "blotter test' is even better. Put a few drops of ATF on a clean paper towel. Wait 30 seconds, then examine the spot. If the fluid has spread out and is pink, red or even light brown in color, the fluid is in satisfactory condition. But if the spot hasn't spread out and is dark brown in color, the ATF is oxidized and should be changed.
The fluid capacity is 6.7 Quarts
